Abstract
A membrane electrode gas diffusion layer assembly for a fuel cell includes a membrane electrode assembly including an electrolyte membrane, an anode catalyst layer, and a cathode catalyst layer, an anode diffusion layer joined to the anode catalyst layer of the membrane electrode assembly, and a cathode diffusion layer joined to the cathode catalyst layer of the membrane electrode assembly, in which at least one of the anode diffusion layer and the cathode diffusion layer includes a microporous layer that makes contact with the membrane electrode assembly, the microporous layer contains a cerium compound, and at least one of the electrolyte membrane, the anode catalyst layer, and the cathode catalyst layer comprises cerium ions.
