Abstract
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.
