Abstract
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 includes 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 a 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.
