Definitions

  • the invention relates to a fuel cell heater according to the Preamble of claim 1.
  • PEM fuel cells polymer membrane fuel cells
  • the two components are particularly in the Use for heating devices for residential buildings in recent years become interesting, especially because with They can provide both heating and electricity at the same time is. In a way, they form an alternative to the classic boiler, with the advantage that the warmth of the Brenners at the same time and thus improve efficiency Generation of hydrogen and ultimately for electricity generation can be used.
  • the resulting (direct) current the is converted into alternating current by means of an inverter, can then either be used directly in the house, but also in the urban electricity grid can be fed.
  • the heat generated is individual components that are not immediately (such as the heat of the heating gas of the burner) in the heat and Power generation process can be integrated, via fans or blowers dissipated to the surroundings of the device.
  • High tightness requirements due to the explosiveness of hydrogen to the appropriate lines, otherwise massive, intolerable safety problems in the event of major leaks can occur.
  • costly sensors are usually required to to detect gas escaping in the event of a fault (for example methane gas).
  • the invention has for its object in a fuel cell heater the problems mentioned at the beginning to meet in a technically simple way, and connected with the stipulation, the efficiency of the device to further increase.
  • the housing to the installation room of the device as completely as possible or at least to train essentially airtight so that accruing Warming the heat and power generation process is not lost not leakage gases that occur in the event of a fault get into the vicinity of the device.
  • both the burner of the gas processing system as well as the fuel cell air or oxygen is mandatory on the housing an air supply independent of room air is provided.
  • Technicus independent of ambient air
  • the only Figure 1 shows a fuel cell heater, the comprises a housing 1, in particular one with a burner 2 heatable, preferably comprising a steam reformer Gas processing system 3 for providing a hydrogen containing gas stream and a fuel cell 4, preferably a PEM fuel cell to convert the hydrogen with the addition of oxygen (usually air) especially in electrical current are arranged.
  • a housing 1 in particular one with a burner 2 heatable, preferably comprising a steam reformer Gas processing system 3 for providing a hydrogen containing gas stream and a fuel cell 4, preferably a PEM fuel cell to convert the hydrogen with the addition of oxygen (usually air) especially in electrical current are arranged.
  • the fuel cell heating device relates due to this requirement any for the Fuel cell process requires air from the free environment (indicated by the tree) or alternatively at least another adjacent room.
  • this has the Advantage that on the one hand all accruing in the device, so far parasitic warmth, but also all at one Accident leakage gases directly into the fuel cell process (including gas treatment) supply and thus can be used to increase efficiency.
  • the air supply 5 optionally from a tube 6 (alternatively a channel or the like is also possible), the an open cross section 7 in the housing 1 and its other open cross section 8 in a with respect to the installation room surrounding the device.
  • the tubular or channel-shaped air supply 5 optionally and with the formation of a (ring) gap 9 from Burner 2 coming exhaust pipe 10 encloses or from this is enclosed.
  • the air supply 5 and the exhaust pipe 10 as Heat exchanger for transferring the exhaust gas heat to the supply air trained, there is even a further increase in efficiency Use of residual exhaust gas heat.
  • the burner 2 is optionally and / or the fuel cell 4 at an open cross section 7 distant point is arranged in the housing 1. This requirement ensures that cold outside air in the Housing 1 is first heated before being burned by burner 2 or the cathode side of the fuel cell 4 is sucked.
  • housing 1 is thermally insulated, which does not require a graphic representation, since without further ado imaginable.
  • all heat-emitting components such as inverters, Gas valves etc. are arranged in the housing 1.
  • anode residual gas combustion when using an authoritative reformer stage to be instructed is also advantageously provided that the burner 2 has a connection for the anode residual gas recirculation with an anode discharge connection of the fuel cell 4 is connected. This ensures that only gas to the burner 2 and the gas processing system 3 and that hydrogen-containing anode residual gas the fuel cell 4 with the burner 2 of the steam reforming stage is combustible.
  • Fan 11 which if necessary (for example when the system is switched off) serves to remove the housing 1 to be flushed with fresh air (post-venting) or to remove a leakage gas To generate negative pressure in the housing 1.
  • the fuel cell 4 for air supply connected on the cathode side to a cathode fan and this at a point distant from the open cross section 7 is arranged in the housing 1. This requirement also ensures that if necessary, cold outside air in the housing 1 is first heated before the cathode side of the fuel cell 4 is fed.
  • the fuel cell 4 supplied cathode air in the housing 1 and by means of preheating a deionized one intended for the fuel cell process Amount of water (for example from the Housing 1 provided deionization system) can be moistened. This ensures that the cathode air is already preheated and pre-moistened in the correct state to the cathode entrance the fuel cell 4 arrives.
