Disclosed is a fuel cell which is characterized by comprising: a membrane electrode assembly (2) which comprises an anode (13), a cathode (16) and an electrolyte membrane (17) interposed between the anode (13) and the cathode (16); a fuel supply mechanism (3) which is arranged on the anode side of the membrane electrode assembly and can supply a fuel to the anode; a cover plate (21) which is arranged on the cathode side of the membrane electrode assembly and is engaged in the fuel supply mechanism by a bending processing; and a stiff member (40) which is arranged between the membrane electrode assembly and the cover plate and has a higher stiffness than that of the cover plate.
