    摘要： A unit cell of a fuel cell includes a membrane electrode assembly and an anode side metal separator and a cathode side metal separator sandwiching the membrane electrode assembly. A plurality of first supply holes and a plurality of second supply holes extend through a channel unit of the anode side metal separator, and the channel unit connects a fuel gas supply passage and a fuel gas flow field. A fuel gas from the fuel gas supply passage flows into the first supply holes, and flows through an inlet connection channel. The fuel gas flows into the second supply holes connected to an end of the inlet connection channel. The fuel gas flows toward the side of the membrane electrode assembly, and then, the fuel gas is supplied to an anode.

Water absorption ratio of the anode diffusion layer at 60° C. is in a range of 40 to 85%, a differential pressure is in a range of 60 to 120 mmaq, and a ratio of quantity of electric charge of catalytic material of the cathode catalytic layer existing in proton conductive passage from the polymer electrolyte membrane is not less than 15% of the quantity of electric charge of all the catalytic material existing in the cathode catalytic layer. Furthermore, a layer including carbon particles having water absorption amount at saturated water vapor pressure at 60° C. of not less than 150 cc/g and fluorine resin, is arranged on a carbon-based material having a contact angle with water of not more than 90° by performing a hydrophilic treatment. The water absorption ratio at 60° C. is in a range of 40 to 85 wt %, and the penetration resistance is not more than 5 mΩ.

    摘要： An electrode for a solid polymer fuel cell includes a gas diffusion layer, an electrode catalyst layer disposed between a solid polymer membrane of the fuel cell and the gas diffusion layer, and a water-holding layer disposed between the gas diffusion layer and the electrode catalyst layer. Under high-relative humidity conditions of reaction gases, flooding can be prevented because the electrode catalyst layer is made porous, while under low-relative humidity conditions of reaction gases, sufficient water contents can be stably provided thanks to the water-holding layer so that proton conductivity of the solid polymer membrane can be maintained appropriately. Consequently, high-performance and high-durability electrode and membrane electrode assembly for a solid polymer fuel cell can be provided such that the performance and the durability thereof are not affected by change in relative humidity in reactant gases supplied to the solid polymer fuel cell.
