Abstract
A fuel cell includes an electrolyte membrane electrode assembly and a resin frame member. The electrolyte membrane electrode assembly includes an electrolyte membrane, a first electrode and a second electrode. The resin frame member has a recess in which the first electrode, the electrolyte membrane, and a portion of a second electrode catalyst layer protruding from a second gas diffusion layer are disposed, and an insertion hole which is in communication with the recess and in which the second gas diffusion layer is inserted. A filling layer covering an outer edge portion of the second electrode catalyst layer and having an oxygen permeability of 2×10ml/m·24 hr·atm or less is formed at least in a space between an inner wall of the insertion hole and the second gas diffusion layer.
