る。 In order to solve this problem, Japanese Patent Application Laid-Open No. 57-157469
Proposals such as those described in Japanese Patent Application Laid-Open No. 57-63775 are known. The former has a structure in which electrolyte is reserved around the separator and refilled from the periphery of the electrolyte plate, while the latter has an electrolyte holding member inserted into the gas supply groove and the electrolyte is supplied to this holding member. When the matrix runs out of electrolyte, the electrolyte is automatically replenished from the holding member by capillary action.

However, according to the former proposal, the size of the battery increases depending on the amount of electrolyte reserved, and although replenishment to the outer periphery of the electrolyte plate is good, it is difficult to replenish evenly to the center. It was hot. In addition, in the latter case, increasing the amount of electrolyte reserved in the gas supply groove increases the effective area of the electrode, and in order to obtain the same output, it is necessary to increase the battery size, which increases manufacturing costs. It was hot. Further, due to the large heat capacity, the amount of heat supplied at startup increases, and there is also the problem of a decrease in thermal efficiency due to an increase in heat dissipation loss.

As described above, the present invention maintains a reserve electrolyte in a portion that does not interact with the battery even when the reaction gas flows, that is, in the entire space formed between the surface of the corrugated current collector plate that does not face the electrode and the separator. Since it is filled with a conductive porous material, all parts of the electrolyte plate can be uniformly replenished with electrolyte without creating a new reserve space. It can supplement the function of the electric board. Furthermore, since the electrolyte is held in a porous body, it is possible to prevent the reserved electrolyte from flowing out, and it is also possible to prevent the reaction gas from flowing into the reserve space. Furthermore, unlike those that utilize gravity to move the electrolyte by capillary force, reservoirs can be provided both above and below the electrolyte plate, making it possible to increase the amount of reserve and extend the lifespan.

Corrugated current collector plates 9 and 10 are provided on the upper and lower surfaces of the separator 4, respectively, and the corrugated current collector plate 9 in contact with the anode 2 has a fuel flow path 6 for supplying fuel gas 5 to the anode 2.
However, in the corrugated current collector plate 10 in contact with the cathode 3, oxidizing agent channels 8 for supplying oxidizing gas to the cathode 3 are formed so as to be orthogonal to each other. Further, an electrolyte reservoir 11 storing electrolyte for replenishment is provided in the entire space formed by the surfaces of the corrugated current collector plates 9 and 10 that do not face the electrodes and the separator 4. ,10
A large number of electrolyte replenishment holes 12 are formed on the surface in contact with the electrodes 2 and 3. This electrolyte reservoir 11
is made of a porous body of metal such as Ni, Cu, Al, etc. that is chemically stable to electrolytes, and the electrolyte is held in the pores of this porous body. In addition, the pore diameter formed in the electrolyte reservoir 11 is larger than the pore diameter formed in the electrodes 2 and 3 and the electrolyte plate 1, so that when the electrolyte in the electrolyte plate becomes insufficient, capillary action automatically removes the electrode from the reservoir. Electrolyte is replenished to the electrolyte plate 1 via 2 and 3. Further, the electrolyte reservoir 11 has conductivity and also has the function of electrically connecting both the anode 2 and cathode 3 and the separator 4.

It is possible to compensate for the consumption of electrolyte in the plate 1, and has the effect of extending the battery life. In addition, since the electrolyte reservoir 11 has conductivity, it also supplements the function of the corrugated current collector plates 9 and 10 that electrically connect the electrodes 2 and 3 and the separator 4, and has the effect of reducing battery internal resistance and improving battery performance. There is also. Furthermore, the space constituting the electrolyte reservoir 11 is a space that should be closed with a closing plate or the like to prevent the gas from flowing, since it does not participate in the cell reaction even if the reaction gas flows. It also acts as a closing plate to stop the gas flow. Furthermore, the battery size is not increased due to the provision of a reserve space, and the battery is compact, reducing manufacturing costs and improving thermal efficiency by reducing heat dissipation.

5 is provided, and the electrolyte is pushed out from the electrolyte reservoir 11 by applying pressure to this communicating path from the outside, thereby replenishing the electrolyte to the electrolyte plate 1. In this case, as shown in FIG. 5, a fuel inlet manifold 16, an oxidizer inlet manifold 17, a fuel outlet manifold 18, and an oxidizer outlet manifold 19 are provided on the four sides of the cell for supplying and discharging the reactant gas, respectively. ing.

When the communication passages 13, 14, 1 are connected from the manifold 20
5, the electrolyte reservoir 11 can be replenished with electrolyte. Furthermore, since the pore diameter of the porous body forming the electrolyte reservoir 11 is smaller than the pore diameter of the electrodes 2 and 3, the electrolyte in the reservoir will not be sucked out toward the electrodes 1 and 2 without pressurization. do not have.

の信頼性が向上した。 FIG. 6 shows a third embodiment of the present invention. In this embodiment, the electrolyte reservoir 11 is provided only on the anode 2 side, and is not provided on the cathode 3 side, and a cooling gas flow path 21 is formed through which oxidizing gas flows to cool the battery. Generally, due to the relationship between gas composition and utilization rate, the flow rate of the oxidant gas flowing through the cathode side is higher than that of the fuel gas flowing through the anode side. In addition, in the case of a cooling method that attempts to cool the battery by supplying a reactive gas with a temperature lower than that of the battery,
Since the oxidant gas is generally used, the flow rate of the oxidant gas increases further. Therefore, the gas flow rate in the oxidizer flow path becomes higher than the gas flow rate in the fuel flow path, and a pressure difference occurs between the fuel side and the oxidizer side within the cell, resulting in a gas crossover in which the fuel and oxidizer mix through the electrolyte plate 1. It causes. Therefore, by using the reservoir space on the cathode 3 side as the cooling gas flow path 21 and flowing the oxidizing gas there, the cross-sectional area of the oxidizing gas flow path is doubled, pressure loss is reduced, and the fuel gas and oxidizing gas are The pressure difference between
As a result, the risk of gas crossover is reduced and battery reliability is improved.

The battery can be operated safely.
