Field of the Invention The present invention relates to a fuel cell using pure hydrogen as a fuel or a reducing agent such as reformed hydrogen from methanol and fossil fuel and using air or oxygen as an oxidant, and particularly to a solid-state fuel cell.

In the H 2 O negative electrode, hydrogen dissociates into protons and electrons. Protons move in the cation exchange membrane toward the positive electrode, and electrons move in the cell laminated in series with the conductive separator plate and an external circuit to reach the positive electrode. At this time, power is generated. On the other hand, in the positive electrode, the protons moving in the cation exchange membrane, the electrons moving in the external circuit, and oxygen introduced from the outside react to generate water. Since this reaction is exothermic, hydrogen, oxygen, and electricity generate electricity, water, and heat as a whole.

工が必要であった。The solid polymer electrolyte fuel cell is greatly different from other fuel cells in that the electrolyte is composed of an ion exchange membrane which is a solid polymer. A perfluorocarbon sulfonic acid membrane (trade name, Nafion, manufactured by DuPont, USA) is used as the ion exchange membrane, but the membrane is sufficiently hydrated in order for this membrane to exhibit sufficient proton conductivity. There is a need. As a method for hydrating the ion exchange membrane, for example, J. Electrochem. So
c. 135 (1988) 2209, a method is adopted in which water vapor is introduced into the cell by passing the reaction gas through a humidifier to prevent the ion exchange membrane from drying. As a method of sealing each cell, for example, J. Po
As described in Wer Sources, 29 (1990) 367, the area of the ion exchange membrane is made larger than the electrode area, and the peripheral portion of the ion exchange membrane that is not joined to the electrodes is sandwiched by upper and lower gaskets. As the material of the gasket, glass fiber cloth or fluorine rubber coated with polytetrafluoroethylene (trade name Teflon manufactured by DuPont, USA) is used. Further, in U.S. Pat. No. 4,826,741, silicon rubber and fluorine rubber are used. In this structure, the gasket must absorb the thickness of the ion exchange membrane of about 150 to 200 μm and perform insulation and gas sealing between the adjacent separator plates. Therefore, it is necessary to perform fine processing by increasing the cell clamping pressure to crush the gasket, or to reduce the thickness of the portion of the gasket that contacts the ion exchange membrane by the thickness of the membrane.

いた。However, in the above-mentioned conventional method, as the number of laminated cells increases, the thickness of the ion-exchange membrane to be absorbed increases and becomes too large to be absorbed completely. And other housings such as end plates and bolts and nuts become large in order to secure strength. In addition, there is a drawback that sufficient gas sealability cannot be secured due to variations in the thickness of the gasket, the ion exchange membrane, and the separator plate. Furthermore, since the ion-exchange membrane changes its thickness with the change of water content, the conventional gasket material has a large stress relaxation property, so there is a risk that the sealing property initially secured will deteriorate during operation.

In the battery, the gasket shall be a closed-cell sponge sheet. In addition, it shall consist of a gasket with an integrated structure in which sponge sheets with closed cells are adhered to both sides of the metal substrate. Further, the gasket has an integral structure in which rubber sheets are adhered to both surfaces of the metal substrate, and a mountain-shaped embossing is applied to the periphery of the sheet portion of the gasket.

様の線状のシールが可能となる。In the first configuration, the closed-cell sponge sheet absorbs the thickness of the ion exchange membrane by compressing the bubbles. In addition, since individual independent air bubbles are compressed against partial unevenness, the swell and roughness of the separator plate can be absorbed. Further, since the closed air bubbles are compressed, stress relaxation is small. In the second configuration, since the closed-cell sponge sheet is bonded to the metal substrate,
Even when a high-pressure gas is used inside, the sponge sheet does not escape to the outside due to the adhesive force between the substrate and the sheet. Since a metal plate is used as the substrate, highly accurate processing is possible. For example, when an aluminum plate or the like is used as the substrate, punching with a Thomson die is easy. In the third configuration, a linear seal similar to that of the O-ring can be obtained by embossing the mountain shape around the seal portion.

Both the ion exchange membrane and the separator could be sealed. The tightening pressure required a sealing pressure of 10 kg / cm 2 when the conventional bubble-free fluororubber was used, whereas 3 kg / cm 2 or more was sufficient for the gasket of the present invention.

Further, the gasket has an integrated structure in which rubber sheets are adhered to both sides of the metal substrate, and a mountain-shaped embossing process is performed around the seal portion of the gasket.

In the second configuration, since the closed-cell sponge sheet is bonded to the metal substrate, the sponge sheet does not escape to the outside due to the adhesive force even when high-pressure gas is used inside. Since a metal plate is used as the substrate, highly accurate processing is possible.
