A fuel cell includes a membrane electrode assembly having electrodes disposed on both surfaces of an electrolyte membrane, a gas diffusion layer stacked on one surface of the membrane electrode assembly, a resin frame assembled onto the one surface of the membrane electrode assembly so as to surround the outer periphery of the gas diffusion layer apart from the outer periphery of the gas diffusion layer, and a resin sheet disposed between the gas diffusion layer and the resin frame, and the membrane electrode assembly so as to fill a space between the inner periphery of the resin frame and the outer periphery of the gas diffusion layer.

Fuel cell and manufacturing method of the same

A fuel cell includes: a membrane electrode assembly of a flat plate shape including an electrolyte membrane and an electrode catalyst layer, the membrane electrode assembly having a first side intersecting a flow pathway of a reactive gas on a surface of the fuel cell and a second side differing from the first side; a frame member of a flat plate shape including an opening part for arrangement of the membrane electrode assembly, the opening part having a first frame side corresponding to the first side and a second frame side corresponding to the second side; and an adhesive member for bonding between an outer periphery of the membrane electrode assembly and an inner periphery of the frame member. The thickness of the adhesive member in an area from an inner peripheral edge at the second frame side toward a center of the frame member may be greater than the thickness of the adhesive member in an area from an inner peripheral edge at the first frame side toward the center of the frame member.
