    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.

    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.

    Abstract: A method for preparing a fuel cell membrane electrode assembly, where the membrane electrode assembly includes a solid polymer electrolyte membrane and a first electrode and a second electrode provided on both sides of the solid polymer electrolyte membrane. The first electrode and the second electrode each include an electrode catalyst layer and a gas diffusion layer. The method includes forming the first electrode and the second electrode on both sides of the solid polymer electrolyte membrane, providing a preformed resin frame member around the solid polymer electrolyte membrane, overlapping an outer marginal portion of the first electrode and an inner marginal portion of the resin frame member with each other and applying heat and pressure to the overlapped portions of the first electrode and the resin frame member to join the resin frame member around the solid polymer electrolyte membrane.

    Abstract: A fuel cell includes an electrolyte-electrode assembly, a frame member, a first separator, and a second separator. The frame member is provided to face a first surface of the second separator and includes a resin wall which forms a periphery of a first reactant gas passage. The resin wall has a thin-walled portion which overlaps with a cooling medium connecting portion in a stacking direction and which protrudes toward the first reactant gas passage in the stacking direction by a first dimension from a surface of the frame member. Another portion of the resin wall protrudes toward the second separator in the stacking direction by a second dimension from the surface of the frame member. The first dimension is smaller than the second dimension.
