Abstract
A frame equipped membrane electrode assembly includes a membrane electrode assembly and a frame member having a first frame shaped sheet provided on an outer peripheral portion of the membrane electrode assembly over the entire periphery. An outer peripheral portion of an electrolyte membrane is provided between a cathode and the first frame shaped sheet, stacked on an outer peripheral portion of the cathode, and joined to an inner peripheral portion of the first frame shaped sheet through an adhesive layer. The adhesive layer is filled in an area surrounded by an inner peripheral end of the first frame shaped sheet, an anode, and the electrolyte membrane.
