CATALYST LAYER FOR GAS DIFFUSION ELECTRODE, METHOD FOR MANUFACTURING THE SAME, MEMBRANE ELECTRODE ASSEMBLY, AND FUEL CELL

摘要

Provided is a catalyst layer for gas diffusion electrode that can be used without using carbon supports, a method for manufacturing the same, a membrane electrode assembly, and a fuel cell. The catalyst layer for gas diffusion electrode according to the present invention include a network-like metallic catalyst formed of a sintered body, the network-like metallic catalyst including nanoparticles linked with each other to have electron conductivity; and an ion conductor, at least a part of the ion conductor contacting the network-like metallic catalyst. Further, the membrane electrode assembly according to the present invention includes a polymer electrolyte membrane provided between an anode catalyst layer and cathode catalyst layer, and the catalyst layer for gas diffusion electrode stated above is used in at least one of the anode catalyst layer and the cathode catalyst layer.
