Abstract
A fuel cell includes a membrane electrode assembly (MEA) having an electrolyte membrane and a pair of electrodes arranged on both sides of the electrolyte membrane in the thickness direction, a pair of frames having a frame shape and holding an outer periphery portion of the electrolyte membrane, a pair of gas diffusion layers arranged inside the pair of frames and on both sides of the MEA in the thickness direction, and a gasket covering at least a part of the pair of frames. The fuel cell further includes a first cross-linking adhesive member formed of rubber which includes a membrane accommodating portion having an indented shape for accommodating the outer periphery portion of the electrolyte membrane and a first intermediate portion interposed between the pair of frames and which is subjected to cross-linking adhesion with the outer periphery portion of the electrolyte membrane and the pair of frames.
