A fuel cell is provided with a membrane-electrode assembly 15 in which catalyst layers 15b as a pair of electrodes are bonded to both the surfaces of an electrolyte membrane 15a, and diffusion layers 16 arranged on both the surfaces of this membrane-electrode assembly 15. The membrane-electrode assembly 15 and the diffusion layer 16s are laminated without bonding at least a part between the membrane-electrode assembly 15 and the diffusion layers 16. Thus, sliding and separating between the catalyst layer 15b and the diffusion layers 16 are allowed.
