Definitions
- the present invention relates to a water separator for a fuel cell system, wherein the water separator has an inlet opening for an anode discharge section of the fuel cell system for admitting anode exhaust gas from the fuel cell system, a storage volume for storing water separated from the anode exhaust gas and an outlet opening for discharging the water stored in the storage volume . Furthermore, the invention also relates to a fuel cell system with such a water separator, an ultrasonic measuring system for a water separator and a measuring method for the water separator, the fuel cell system or the ultrasonic measuring system.
- Cost-intensive mass spectrometers are currently used to measure the concentration of hydrogen, which generally permanently extract gas from the anode volume in the fuel cell stack, which should be avoided.
- a water separator for a fuel cell system wherein the water separator has an inlet opening for an anode discharge section of the fuel cell system for admitting anode exhaust gas from the fuel cell system, a storage volume for storing water separated from the anode exhaust gas, and an outlet opening for discharging the water stored in the storage volume.
- the water separator further has an ultrasonic measuring system with at least one ultrasonic sensor for measuring a water level of the water, in particular in the storage volume, and for measuring a hydrogen concentration of the anode exhaust gas, in particular in the storage volume.
- an ultrasonic measuring system which can measure both the water level of the water separator and the hydrogen concentration in the water separator with one or more sensors in a water separator.
- no different measuring systems and sensors are necessary.
- the provision according to the invention of the single measuring system for both measurements therefore not only allows a compact use of installation space within and/or on the water separator and thus in the fuel cell system, but is also cost-effective and allows a particularly precise measurement using the same ultrasonic measuring principle.
- This measuring principle is included robust to the operating conditions in the anode loop with the liquid water droplets. It can also be built very compactly to further minimize the space required. Providing two measurement options also improves the calibration and thus the optimization of the fuel cell system.
- a first ultrasonic sensor is set up to measure the water level of the water and a second ultrasonic sensor is set up to measure the hydrogen concentration of the anode exhaust gas.
- the ultrasonic measuring system has at least two ultrasonic sensors, each of which can carry out different types of measurements, which are later also referred to as level measurements and concentration measurements.
- the devices of the sensors for these different measuring tasks can be implemented, for example, through their structure, their relative positioning or the positioning of their measuring direction and/or additional possible elements, such as measuring element surfaces. This advantageously allows both the water level and the hydrogen concentration to be measured at the same time, so that these can also be permanently monitored.
- the wall section can be, for example, a side wall, in particular an inner side wall, of the water separator. This enables a comparatively particularly compact design because the ultrasonic sensors do not have to be far from each other and therefore from other measuring system components, which in turn would require additional installation space, for example due to appropriate cabling, and would result in additional costs.
- the two ultrasonic sensors are arranged next to each other. This means that the two ultrasonic sensors are in close proximity to each other. This also allows the previously mentioned compact structure.
- the ultrasonic measuring system has at least one measuring system component, which the two ultrasonic sensors at least partially share.
- Such at least one measuring system component can be, for example, a measuring control device, cabling, a power supply, etc. Because the two ultrasonic sensors share at least one, several or all of the measuring system components that are required for the measurements, a redundancy in the measuring system components that is conducive to a possible failure of components can be achieved in favor of a compact and cost-effective structure of the ultrasonic measuring system and thus the fuel cell system in which it is used can be avoided.
- the at least one ultrasonic sensor and/or one measuring element surface of the ultrasonic measuring system is mounted movably between two measuring positions in order to measure the water level of the water in a level measuring position of the two measuring positions and in a concentration measuring position to measure the hydrogen concentration of the anode exhaust gas in both measuring positions.
- the movable bearing can be provided, for example, by a rotary bearing and/or translational bearing, which enables rotation or translational movement of the at least one ultrasonic sensor and/or the measuring element surface.
- a drive can be provided on the measuring element surface and/or the at least one ultrasonic sensor, which is correspondingly controlled by the ultrasonic measuring system in order to provide one of the two measuring positions.
- the ultrasonic measuring system can also be equipped with just one ultrasonic sensor, which can carry out both types of measurements depending on the selected measuring position.
- a precise measurement typically only a time-separated measurement of the water level and concentration measurement will be possible.
- the at least one ultrasonic sensor has a measuring direction aligned with a water surface of the water stored in the storage volume for measuring the hydrogen concentration of the anode exhaust gas. Equipped with this measuring direction, the ultrasonic sensor can determine the distance between the at least one ultrasonic sensor and the water surface as the level of the storage volume. This distance can be assigned to a water level if the dimensions of the water separator are known. For example, a formula, a mapping table or the like can be used by the ultrasound Assign a water level to the distance measured by the sensor, which can be determined by the ultrasonic measuring system.
- the fill level measuring position can in particular be a measuring position in which the measuring direction of the ultrasonic sensor is aligned with the water surface.
- the at least one ultrasonic sensor has a measuring direction for measuring the hydrogen concentration that is aligned with a measuring element surface of the ultrasonic measuring system in the water separator. This means that the hydrogen concentration can be measured in particular in a different measuring direction than that for measuring the water level.
- the measurement of the hydrogen concentration is carried out in the same measuring direction as the measurement of the water level.
- a fixed geometry can advantageously be present in the “viewing direction” of the sound source (next to the water surface, i.e. the “measuring element surface”) and the two different signals (fill level and concentration) can be separated through appropriate signal analysis and/or processing.
- the measuring element surface can preferably be arranged on a measuring element within the water separator, in particular within the storage volume.
- a measuring element can, for example, protrude from an inner wall of the water separator towards the inside of the water separator, in particular into the storage volume, or can be designed as an inner wall of the water separator.
- the measuring element can be made of a solid material, for example plastic, metal or the like, which preferably has sufficient resistive properties for use in the water separator, that is, for example, can have a specific coating.
- the measuring element can also be made of the same material as the wall of the water separator, in particular designed in one piece with it.
- the measuring element surface can advantageously have a predetermined distance from the at least one ultrasonic sensor. Because the distance is predetermined, it is always known and so the ultrasound emitted by the ultrasonic sensor requires a different amount of time at different hydrogen concentrations until it is reflected by the measuring element surface and is registered again at the ultrasonic sensor. Here too you can For example, a formula, an assignment table or the like for the respective period of time from transmission to reception of the ultrasound can be assigned to a hydrogen concentration, which can be determined by the ultrasound measuring system. In the case of a movably mounted measuring element surface, the distance can optionally also be adjustable, although the distance is known through a measurement or predetermined storage positions of the measuring element surface.
- the present invention also relates to a fuel cell system, comprising at least one fuel cell stack with an anode section and a cathode section, an anode supply section for supplying anode supply gas to the anode section, a cathode supply section for supplying cathode supply gas to the cathode section, an anode discharge section for discharging anode exhaust gas, and a cathode discharge section for Discharging cathode exhaust gas, with a water separator according to the invention being arranged in the anode discharge section.
- the fuel cell system thus brings with it the same advantages as have been explained in detail with reference to the water separator according to the invention.
- the fuel cell system can be of any type, for example of the polymer electrolyte membrane (PEM for short) type.
- the present invention also relates to an ultrasonic measuring system for a water separator, in particular the water separator according to the invention, for a fuel cell system, in particular the fuel cell system according to the invention, wherein the ultrasonic measuring system has at least one ultrasonic sensor for measuring a water level of water in the water separator and for measuring a hydrogen concentration of an anode exhaust gas in the water separator.
- the subject of the present invention is also a measuring method for the water separator according to the invention, for the fuel cell system according to the invention or for the ultrasonic measuring system according to the invention, whereby the Measuring procedure includes the following steps, each of which is carried out using the ultrasonic measuring system:
- a measuring method according to the invention therefore also brings with it the same advantages as have been explained in detail with reference to the water separator according to the invention.
- the level measurement and the concentration measurement are carried out at the same time, at least temporarily.
- the level measurement and the concentration measurement are carried out at separate times. This has the advantage that a single ultrasonic sensor can be used for both level measurement and concentration measurement.

- FIG. 1 shows schematically an exemplary embodiment of a fuel cell system 100 according to the invention.
- the fuel cell system 100 is shown here purely as an example with a single fuel cell stack 110 with an anode section 112 and a cathode section 114, although of course several fuel cell stacks 110 can also be provided.
- An anode supply section 120 serves to supply anode supply gas to the anode section 112 and a cathode supply section 140 serves to supply cathode supply gas to the cathode section 114.
- an anode discharge section 122 serves to discharge anode exhaust gas
- a cathode discharge section 142 serves to discharge cathode exhaust gas.
- a water separator 10 is integrated into it, which allows water 1 (see FIG. 2) or, to be more precise, product water from the anode exhaust gas 3 (see FIG. 2) to be separated in the anode discharge section 122.
- This separated water 1 can be discharged via a water outlet 12 of the valve device 30, either out of the fuel cell system 100 or recirculated within the fuel cell system 100 for further use.
- anode supply gas is now introduced into the anode section 112 of the fuel cell stack 110 through the anode supply section 120.
- Spent anode exhaust gas 3 is discharged via the anode discharge section 122 and, as explained, runs through the water separator 10.
- the anode exhaust gas 3 can also be recirculated about the passive one shown Recirculation device, for example in the form of an ejector device 150.
- the water separator 10 can of course also be arranged in the recirculation section 130 or even in the anode supply section 120 downstream of the passive recirculation device here in the form of the ejector device 150.
- FIG 2 shows the water separator 10 from Figure 1 in more detail.
- the water separator 10 is shown in a purely schematic manner as a simple container, which is typically not the case because it is usually constructed in a much more complex manner in order to effectively separate the water 1 therein.
- the illustration only serves to provide a better understanding of the invention.
- the water separator 10 comprises a storage volume 4, illustrated here as an example, for storing the water 1 separated from the anode exhaust gas 3. Furthermore, the water separator 10 comprises an inlet opening 16, which is fluidly connected to the anode discharge section 122. In fact, the anode discharge section 122 is also fluidly connected to the water separator 10 elsewhere. The water separator 10 also includes an outlet opening 14, which is fluidly connected to the water outlet 12 of the valve device 30 in order to be able to discharge water 1 separated and stored from the anode exhaust gas 3.
- the water separator 10 also includes an ultrasonic measuring system 20, which is arranged here, for example, on an upper wall section of the water separator 10 in FIG. 2.
- the ultrasonic measuring system 20 here includes, for example, two ultrasonic sensors 22, 24.
- a first ultrasonic sensor 22 is set up to measure the water level of the water 1. For this purpose, it is aligned in its measuring direction 5 shown with the water surface of the stored water 1 in the storage volume 4. The water surface has a certain water level 2 that needs to be determined. For this purpose, the first ultrasonic sensor 22 sends out ultrasound towards the water surface and receives it after a time that depends on the distance between the first ultrasonic sensor 22 and the water surface. By measuring this time between sending and receiving the ultrasound, the ultrasound measuring system 20 can calculate the water level 2 back.
- a second ultrasonic sensor 24 is set up to measure the hydrogen concentration of the anode exhaust gas 3.
- the ultrasonic measuring system 20 can recalculate the hydrogen concentration in the anode exhaust gas 3 by measuring the time between sending and receiving the ultrasound from the second ultrasonic sensor 24.
- the two ultrasonic sensors 22, 24 here use a common measuring system component 26, which is shown here as an example outside the water separator 10.
- the measuring system component 26 can, for example, be a measuring control device including a power supply.
- FIG. 3 shows an exemplary embodiment in which a single ultrasonic sensor 22 is used to measure both the water level 2 and the hydrogen concentration.
- the ultrasonic sensor 22 is movably mounted, in particular rotatably mounted, so that it can carry out a rotation R, as shown in FIG Ultrasonic sensor 22 can be conveyed.
- position P1 of the ultrasonic sensor 22 shown on the left which is a fill level position P1
- the measuring direction 5 is aligned with the water surface. This makes it possible to measure the water level 2 using ultrasound. If the rotation R is now carried out in the direction shown in FIG. 3, the position P2 indicated on the right in FIG.
- the ultrasonic sensor 22 is aligned with its measuring direction 5 towards the particularly fixed measuring element surface 18, as shown in FIG. 2. This makes it possible to measure the hydrogen concentration in the concentration measuring position P2.
- Changing the measuring direction 5 of the ultrasonic sensor 22 allows both concentration measurement and level measurement.
- the measuring element surface 18 it is also possible to design the measuring element surface 18 to be movable. For example, it is conceivable to move the measuring element surface 18 in front of the ultrasonic sensor 22 to assume the concentration measuring positions P2, so that its measuring direction 5 is aligned with it.
- the measuring element surface 18 can then be moved away from in front of the ultrasonic sensor 22 in order to align its measuring direction 5 again with the water surface. It is therefore also possible not to change the measuring direction 5 itself in order to enable the concentration measurement and the level measurement using only one ultrasonic sensor 22, but rather the surface to be measured in front of the ultrasonic sensor 22 is changed, i.e. the water surface on the one hand and on the other the measuring element surface.
- Figures 4 and 5 show exemplary embodiments of measuring methods 200 that can be carried out by the ultrasonic measuring systems 20 described here.
- the level measurement 202 of the water level 2 of the water 1 and the concentration measurement 204 of the hydrogen concentration of the anode exhaust gas 3 take place one after the other in time.
- This measuring method 200 can relate in particular to the design of the ultrasonic measuring system 20 of FIG. 3.
- the level measurement 202 and the concentration measurement 204 can be used by one and the same ultrasonic sensor 22.
- a movement step 206 can take place between the level measurement 202 and the concentration measurement 204, as shown in FIG. 4.
- the previously explained movement of the ultrasonic sensor 22 and/or the measuring element surface 18 can take place in order to switch between the two measuring positions P1, P2.
- the concentration measurement 204 and then the level measurement 202 can also be carried out the other way around.
- the measuring method 200 shown can also be repeated, for which purpose a movement step 206 can take place between one of the two measuring steps 202, 204 in order to set the respectively required measuring position P1, P2 for the following measuring step 202, 204.
- the level measurement 202 of the water level 2 of the water 1 is carried out by the first ultrasonic sensor 22 2 and the concentration measurement 204 of the hydrogen concentration of the anode exhaust gas 3 by the second ultrasonic sensor 24 in parallel in time.
- this measuring method 200 relates in particular to the exemplary embodiment of the ultrasonic measuring system 20 of the water separator 10 of FIG. 2.
