PROBLEM TO BE SOLVED: To integrate an electrolyte/electrode structure and a separator by fusing a resin frame member, and to impart an appropriate surface pressure reliably to the electrolyte/electrode structure.SOLUTION: In the manufacturing method of a fuel cell 10, while sandwiching a metal separator 12 between a pair of electrolyte membrane/electrode structures 14, the electrode part of the electrolyte membrane/electrode structure 14 is pressed in the lamination direction, and a protrusion 22b provided in a thick portion 22a of a frame 22 is fused while deforming the electrolyte membrane/electrode structure 14 so that a prescribed surface pressure is applied. Fusion processing of the frame 22 is continued until the protrusion 22b of the frame 22 is fused and deformed by the same amount as that of the electrolyte membrane/electrode structure 14, thus integrating the metal separator 12 and the electrolyte membrane/electrode structure 14. |
