Method for manufacturing a fuel cell and a fuel cell and a fuel cell

For the purpose of productivity fewer steps of the molding to provide good fuel cell, an anode electrode (46a) and the cathode electrode (46b) electrode parts formed by providing a polymer electrolyte membrane (44) the edges of the polymer electrolyte membrane is exposed to the outer periphery (44), placed on top of one frame (47a), on its upper surface, the Young's modulus is injected less resin material than one frame (47a) while forming the other frame (47c) Te, the lower surface of the one frame (47a), forming seal portion of the same material as the other frame (47c) and (49) simultaneously.
