Abstract
A membrane electrode assembly includes an MEA structure unit and a resin frame member. The MEA structure unit includes a cathode, an anode, and a solid polymer electrolyte membrane interposed between the cathode and the anode. The resin frame member is formed around the MEA structure unit, and joined to the MEA structure unit. An adhesive layer is provided between an outer marginal portion of the solid polymer electrolyte membrane extending outward beyond an outer end of a second gas diffusion layer and an inner extension of the resin frame member. The adhesive layer includes an overlapped portion overlapped on an outer marginal end of the second gas diffusion layer.
