Definitions
- the present invention relates to electrochemical reactors equipped with a temperature homogenizing device, in particular electrolysers or fuel cells, and more particularly high temperature electrolysers.
- An electrolyser comprises a plurality of elementary cells formed by a cathode and an anode separated by an electrolyte, the elementary cells being connected electrically in series by means of interposed interconnecting plates, generally between an anode of an elementary cell and a cathode of the next elementary cell.
- Anode-anode connection followed by a cathode-cathode connection is also possible.
- Interconnecting plates are electronic conductive components formed by a metal plate. These plates also ensure the separation between the cathodic fluid circulating at the level of an elementary cell of the anode fluid flowing in a next elementary cell.
- the anode and the cathode are porous material in which the gases can flow.
- water vapor circulates at the cathode where is generated hydrogen in gaseous form
- a draining gas circulates at the anode and collects oxygen generated in gaseous form at the anode.
- the current electrolysers have a significant electrical resistance, so that the overall reaction at the electrolyzer is exothermic, while the electrochemical reaction at each cell is endothermic.
- the internal elements of the electrolyzer including the elementary cells, are made at least partly ceramic, they are very sensitive to temperature gradients and are not able to withstand a thermal shock greater than 50 0 C. This therefore implies that the temperature of the incoming gases is not lower than that of the outgoing gases by more than 50 ° C.
- a heat exchanger is used upstream of the electrolyser as described in the document "Concepts and Design for scaling up high temperature water vapor electrolysis", W Doenits and R. Schmidberger, in Int. . J. Hydrogen Energy, Vol.7, No. 4, pp. 321-330. 1982.
- this higher temperature impairs the mechanical strength of the cells and lowers the conversion efficiency.
- a superalloy specially adapted for high temperatures such as Haynes 230 has a price ten times higher than that of a stainless steel usable up to 500 0 C.
- an electrochemical reactor comprising a plurality of stacked elementary cells, connected by interconnecting plates incorporating channels for circulating the incoming gases in the electrochemical reactor prior to their injection into the cathodes and / or the anodes.
- the electrochemical reactor incorporates internal heat exchangers formed directly between the elementary cells.
- the inlet water vapor circulates in the interconnecting plates before circulating in the cathodes; during this circulation it is heated by heat exchange with the gas flowing in the cathodes and with the anodes in contact with the interconnecting plates.
- External exchangers can be simplified and made more compact. It is also no longer necessary to have outgoing gases at a temperature higher than that required for the incoming gases. The homogeneity of temperature within the electrochemical reactor is therefore easier to achieve, the operation of the electrochemical reactor is thus improved.
- the gain in temperature can reach more than 50 0 C
- this integrated circuit in the cells makes it possible to efficiently heat the inlet gas (s) directly and directly from the internal losses of the electrolyser and to homogenize their temperature.
- the fluid circuit produced directly in the interconnecting plates makes it possible to heat the electrolyser with the incoming gases and to avoid the introduction of a coolant and a specific circuit for heating the gas inside the electrolyser.
- the present invention therefore mainly relates to an electrochemical reactor comprising a stack of a plurality of elementary electrolysis cells, each cell being formed of a cathode, an anode and an electrolyte disposed between the cathode and the cathode.
- said electrochemical reactor also comprising means capable of ensuring the circulation at least one pneumatic fluid intended to come into contact with the cathodes and / or the anodes in the electrochemical reactor to heat it before it comes into contact with the cathodes and / or the anodes.
- Said circulation means comprise for example at least one duct for the circulation of the pneumatic fluid so that heat exchanges between the pneumatic fluid and the cathodes and / or the anodes take place.
- the duct may be formed in the interconnecting plate, a first end of said duct being connected to a pneumatic fluid supply and a second end bringing the heated pneumatic fluid into contact with one or the other of the electrodes in contact with the interconnecting plate .
- the conduit is interposed between the interconnecting plate and one and / or the other of the electrodes.
- the circulation means comprise a first conduit for the circulation of a pneumatic fluid intended to come into contact with one of the two electrodes, and a second conduit for the circulation of a pneumatic fluid intended to come in contact with the other electrode.
- the first and second conduits may be made in the interconnecting plate, or the first conduit may be interposed between the interconnecting plate and one of the electrodes and the second conduit may be interposed between the interconnecting plate and the other electrode.
- the pneumatic fluid intended to come into contact with the cathode is water vapor
- the reactor then performing the electrolysis of the water to generate hydrogen.
- the reactor is, for example, designed to operate at high temperature, advantageously greater than 900 ° C.
- the present invention also relates to an electrolysis installation comprising an electrolyzer according to the present invention and a heat exchanger upstream of the electrochemical reactor in which the incoming pneumatic fluids and the outgoing pneumatic fluids circulate separately, so as to heat the fluids incoming tires from outgoing pneumatic fluids.
- the present invention also relates to a method of electrolysis of a pneumatic fluid implementing an electrochemical reactor according to the present invention, comprising the steps of: a) circulation of the pneumatic fluid between an electrode of an elementary cell and an electrode an adjacent elementary cell without contact therewith for heating said pneumatic fluid, b) injecting the heated pneumatic fluid on one and / or the other of the electrodes.

- an electrolyser of water to produce hydrogen will be described by way of example.
- the invention applies to any other electrochemical reactor such as a fuel cell.
- Each elementary cell comprises an electrolyte disposed between a cathode and an anode.
- the cell C1 comprises a cathode 2.1 and anode 4.1 between which is disposed an electrolyte 6.1, for example solid generally 100 ⁇ m thick.
- Cell C2 comprises a cathode 2.2 and anode 4.2, between which an electrolyte 6.2 is disposed.
- the cathodes 2.1, 2.2 and the anodes 4.1, 4.2 are made of porous material and have for example a thickness of 40 microns.
- the anode 4.1 of the cell C1 is electrically connected to the cathode 2.2 of the cell C2 by an interconnecting plate 8 coming into contact with the anode 4.1 and the cathode 2.2. Furthermore, it allows the power supply of the anode 4.1 and the cathode 2.2.
- An interconnecting plate 8 is interposed between two elementary cells. In the example shown, it is interposed between an anode of an elementary cell and the cathode of the adjacent cell. But one could predict that it is interposed between two anodes or two cathodes.
- the interconnecting plate 8 defines with the adjacent anode and cathode channels for the circulation of fluids. They define anode compartments 9 dedicated to the flow of gases at the anode and cathode compartments 11 dedicated to the flow of gas at the cathode, these being particularly visible in Figure 2.
- the interconnecting plate 8 further comprises at least one duct 10 connected by a first end 10.1 to a pneumatic fluid supply for undergoing reduction. In the example considered, it is steam and at a second end 10.2 of the cathode compartment.
- the interconnecting plate comprises a plurality of conduits 10 and a plurality of anode and cathode compartments.
- the duct 10 and the compartments have hexagonal honeycomb sections, which makes it possible to increase the density of compartments 9, 11 and ducts 10.
- the arrows 12 represent the "cold" water vapor entering the electrolyser and the arrows 14 represent the heated water vapor circulating in the cathode compartment 11.
- the arrows 16 represent the heat transfers of the cathode 2.2 and the anode 4.1 to the interconnecting plate, or more precisely to the "cold" water vapor.
- the arrows 17 symbolize the flow of heated water vapor from the duct 10 to the cathode compartment 11.
- the water vapor possibly preheated, enters the conduit 10; during its displacement in the duct 10, it is heated by heat exchange with the cathode and the anode bordering the interconnecting plate 8.
- a heat exchanger is advantageously provided upstream of the electrolyser for heating the incoming fluid or fluids from the outgoing fluids, however it may advantageously be simpler and less cumbersome than those used in the state of the art, indeed it does not need to have a high temperature stage.
- the duct 10 is connected at the inlet to a source of draining gas intended to circulate in the anode compartment 9, and at the outlet to the anode compartment 9.
- FIGS. 3 and 4 show another embodiment of an electrolyser according to the invention in which an additional duct 18 is provided along the duct 10 and intended to receive a draining gas circulating in the anode compartment 9.
- the arrows 20 represent the draining gas
- the arrows 24 represent the heat transfer from the cathode 2.2 to the interconnecting plate, or more precisely the "cold" water vapor
- the arrows 26 represent the heat transfer from the anode 4.1 to the interconnecting plate, more precisely to the draining gas.
- the arrow 25 symbolizes the flow of the draining gas from the conduit 18 to the anode compartment 9. This flow is in no way necessary, this gas could be used in other areas or even outside the reactor.
- the water vapor possibly preheated, enters the conduit 10; during its displacement in the duct 10, it is heated by heat exchange with the cathode bordering the interconnecting plate 8.
- This vapor heated to a temperature close to that of the cell C1 then enters the cathode compartment 11, in which it undergoes a reduction; hydrogen is then generated.
- the draining gas optionally preheated, enters the duct 18, while it is moving in the duct 18, it is heated by heat exchange with the anode bordering the interconnecting plate 8. This gas heated to a temperature close to that of the Cl cell it then enters the anode compartment 9, and carries the oxygen generated at the anode.
- the interconnector plates are massive and the channels are made directly therein.
- FIG. 5 representing another embodiment of an integrated heat exchanger according to the invention
- the exchanger is disposed on the interconnecting plate.
- an electrochemical cell C1 a coil 28 formed of a hollow tube, the latter being in contact with an electrode of the cell, and the interconnecting plate 8.
- the pneumatic fluid enters the coil 28 through an end 28.1, circulates in the coil 28 before flowing out of it by one end 28.2 and spread on the electrode.
- the fluid is water vapor.
- the coil is advantageously made of electrically conductive material to participate in the electrical connection between the cathode of the cell C1 and the interconnecting plate. It is recalled that the interconnecting plate also serves to separate the cathode fluid from an elementary cell of an anode fluid from an adjacent elementary cell.
- a coil (not shown) is interposed between the anode and the interconnecting plate.
- the present invention therefore consists in providing means capable of heating at least a portion of the incoming gases in the electrolyser before being brought into contact with the cathode or the anode.
- the dimensions of the heat exchanger circuits are of the same order of magnitude as those of the cathode and / or anode circuits, since they are the same fluids and the same flows circulating in these different circuits.
- part of the heat exchanger is integrated directly into the electrolyser, in particular the hottest part thereof.
- the high temperature fluid indicator area is then limited to the electrolyser, so the amount of material for making the parts to come into contact with the high temperature fluids is reduced.
- the cost of the material can thus be divided by five or even ten compared to the facilities of the state of the art.
- the temperature differences in the electrolyser are also reduced. Moreover, since the heat transport distance from the hot source (the reactor cell) to the exchanger is reduced, temperature differences of less than 50 ° C. can be obtained.
- the interconnecting plate is at a lower temperature than that of the cell, of at least 50 ° C.
- the interconnecting plate is for example made of iron or nickel, and contains elements such as chromium. This chromium tends to pass through the gases and pollutes the electrodes.
- elements such as chromium.
- This chromium tends to pass through the gases and pollutes the electrodes.
- the present invention because of the lowering of the temperature, there is a decrease in the volatilization of the alloying elements and therefore a decrease in pollutant emissions from polluting the electrodes of the cell; it should be noted that these emissions increase exponentially with temperature according to Arhismeus' law.
- the lifespan of the stack of cells is generally increased because of the drop in operating temperature.
- P. Batfalsky in Journal of Power Sources 155, 2006, pp. 128-13 shows that the lifetime of an electrolyser of the state of the art can be multiplied by ten or even twenty by lowering the temperature from 800 0 C to 700 0 C.
- the difference between the minimum and maximum temperatures of the cell can be reduced to values of less than about ten degrees, the operation of the electrolyser is thus improved.
- the inlet and outlet temperature of the gases may be lower, which may allow the electrolyser to be connected to lower temperature circuits of less than 600 ° C., only the electrolyser being at its core at a high temperature, this which allows the use of valves and instrumentations current and less expensive.
- the exchanger according to the invention and the junction circuits to the electrolyser may furthermore be of simpler and less expensive design. Thermal losses are also lower.
- This exchanger operates in a temperature range less constraining in terms of material and overall efficiency of the heat exchange.
- the invention allows the electrolyser to be heated inside the same because of the presence of the heat exchanger inside the electrolyser.
- the temperature rise of the inlet gases is limited and the electrolyser offers a better efficiency.
