Abstract:
A resin-framed membrane-electrode assembly for a fuel cell includes a stepped membrane-electrode assembly and a resin frame member. The stepped membrane-electrode assembly includes a polymer electrolyte membrane, a first electrode, and a second electrode. The resin frame member surrounds an outer perimeter of the polymer electrolyte membrane and includes an inner perimeter base end and an inner protruding portion. The inner protruding portion includes a flat surface portion which extends to face an outer perimeter surface portion of a second surface of the polymer electrolyte membrane and on which an adhesive layer is provided so that the adhesive layer lies at least between the flat surface portion and the outer perimeter surface portion. The adhesive layer has a tapered shape in which a thickness of the adhesive layer increases from a tip of the inner protruding portion toward the inner perimeter base end.
