    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.

    摘要： A solid polymer electrolyte fuel cell has a fuel electrode and an oxidant electrode, which face each other via a solid polymer electrolyte membrane. A metallic complex is added to the fuel electrode of the solid polymer electrolyte fuel cell. Since this metallic complex adsorbs oxygen as the oxygen partial pressure at the fuel electrode increases and desorbs oxygen as the oxygen partial pressure decreases, oxygen produced when a reverse voltage is generated can be removed efficiently. It may be possible to prevent the deterioration of or damage to a catalyst material of the fuel cell and the electrolyte membrane.
