    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 membrane electrode assembly for a polymer electrolyte fuel cell has, as basic components, a polymer electrolyte membrane, a pair of electrode layers which sandwich the polymer electrolyte membrane, and a pair of gas-diffusion layers disposed outside the respective electrode layers. Electric medium layers are respectively provided between the electrode layer and the gas-diffusion layer at one side and between the electric layer and the gas-diffusion layer at the other side. Each of the electric medium layers is constituted of a plurality of carbon whiskers, a plurality of carbon particles and a binder including an electrolyte material. A content G w of the carbon whiskers in each of the electric medium layers is set at 10wt% ≤ G W ≤ 25wt%. Thus, the membrane electrode assembly for the polymer electrolyte fuel cell can keep a high power generating performance by reducing the contact resistance between the gas-diffusion layers and the electrode layers.

    摘要： A membrane-electrode structure capable of exhibiting excellent electric power generation performance even in a high current region and a polymer electrolyte fuel cell using the membrane-electrode structure are provided. Additionally, electric appliances and transport machines each using the above-described polymer electrolyte fuel cell are provided. The membrane-electrode structure comprises an anode electrode 2a, a cathode electrode 2b and a polymer electrolyte membrane 3 made of a sulfonated polyarylene based polymer and held between both electrodes 2a, 2b. The cathode electrode 2b comprises an electrode catalyst layer 4b containing a catalyst particle having the catalyst loaded on the carbon particles, a pore forming member and an ion conducting polymer falling within the weight ratio range from 1.0 to 1.8 in relation to said carbon particles, and is in contact with the polymer electrolyte membrane 3 through the electrode catalyst layer 4b. The electrode catalyst layer 4b has a total sum volume of the pores falling within the pore diameter range from 0.01 to 30 µm, of the pores formed by the pore forming member, equal to or more than 6.0 µl/cm 2 ·mg catalyst. The pores formed by said pore forming member have a first peak falling within the pore diameter range from 0.01 to 0.1 µm and a second peak falling within the pore diameter range from 0.1 to 1.0 µm.
