A fuel cell electrode and method of manufacturing a fuel cell electrode, membrane electrode assembly, and methods of manufacturing the membrane electrode assembly and solid polymer fuel cell

摘要

With the use of a fuel cell electrode in which a binder layer (buffer layer) containing a thickening agent is provided on a gas diffusion layer and an electrode catalyst layer containing catalyst particles and a polymer electrolyte is laminated on the binder layer (buffer layer), it is possible to provide: a fuel cell electrode in which the adhesivity between a gas diffusion layer made of carbon paper or carbon cloth and an electrode catalyst layer containing catalyst particles and a polymer electrolyte is improved and delamination of or crack generation in an electrode catalyst layer does not occur; a membrane-electrode assembly (MEA) comprising the fuel cell electrode; and a solid polymer fuel cell comprising the membrane-electrode assembly.
