Abstract

Official abstract text for this publication.

A membrane electrode assembly for a fuel cell includes a membrane electrode assembly and a resin frame member. The membrane electrode assembly includes a solid polymer electrolyte membrane, a first electrode, and a second electrode. The first electrode includes a first catalyst layer and a first gas diffusion layer. The second electrode includes a second catalyst layer and a second gas diffusion layer. The resin frame member includes an outer peripheral portion and an inner peripheral projection. A first space includes a gap between an outer peripheral end face of the second gas diffusion layer and an inner-side end face of the inner peripheral projection. A second space includes a gap between an outer peripheral end face of the first gas diffusion layer and an inner-side wall face of the outer peripheral portion. The first space has a dimension different from a dimension of the second space.
