The present invention also provides a polymer electrolyte fuel cell that uses the membrane-electrode structure, and an electric apparatus and a transport apparatus that use the polymer electrolyte fuel cell. The solid polymer electrolyte membrane 2 is sandwiched by catalyst layers 3 and 4 positioned in the inner circumferential side thereof, and one face is coated with the catalyst layers 3 and 4 and the adhesive support layer 9. The adhesive support layer 9 is formed of an adhesive that has fluorine atoms in the molecular structure. The adhesive has a tensile elongation at break of 150% or more after curing. Having porous diffusion layers 5 and 6 that coat the catalyst layers 3, 4 and the adhesive support layer 9, the adhesive support layer 9 is integrated with the diffusion layer 6 through adhesive permeating layers 10. Irregularity that has a maximum height Rmax of surface roughness within a range between 3 and 20 μm is formed on the area coated by the adhesive support layer 9 of the solid polymer electrolyte membrane 2, and the adhesive support layer 9 is bonded to the area where the irregularity has been formed by pressing under heating.

    摘要: A membrane-electrode structure having an electrode catalyst layer adhered to a diffusion electrode, wherein the structure is manufactured by applying a catalyst paste onto a sheet substrate, and then dried to form a plurality of electrode catalyst layers. The electrode catalyst layers are thermally transferred onto each side of a polymer electrolyte membrane to form a laminated body. A first slurry is applied on a carbon substrate layer, and dried to form a water-repellent layer, and then, a second slurry is applied on the water-repellent layer, and dried to form a hydrophilic layer to form a diffusion electrode. The diffusion electrode is then laminated on the electrode catalyst layer through the hydrophilic layer, and then pressed under heating to integrate the laminated body and the diffusion electrode.

    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 GW of the carbon whiskers in each of the electric medium layers is set at 10 wt %≦GW≦25 wt %. 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.
