Abstract
In one embodiment, a membrane electrode assembly comprises a catalyst layer being porous and containing a catalyst material, the catalyst layer comprising a plurality of catalyst units each having a porous body structure or a laminated structure containing a void layer, and an electrolyte membrane adjacent to the porous catalyst layer. The catalyst unit bites into the electrolyte membrane, and an average biting ratio is not less than 10%, and not more than 80% of a thickness of the catalyst layer.
