MANUFACTURING METHOD OF METALLIC SEPARATOR FOR FUEL CELL, MANUFACTURING DEVICE, AND LAMINATED PLATE MATERIAL FOR METALLIC SEPARATOR FOR FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide the manufacturing method of a metallic separator for a fuel cell suppressing increase in a manufacturing cost by reducing the number of molds and increasing sealing performance; to provide a manufacturing device; and to provide a laminated plate material for the metallic separator for the fuel cell.

SOLUTION: The metallic separator 30 for the fuel cell is manufactured in such a way that the laminated plate material 60 is put in a mold 51 comprising a upper mold 53 having a recessed part 53a for a fuel electrode for forming the metallic separator on the fuel electrode side and a lower mold 54 having a recessed part 54a for an air electrode for forming the metallic separator on the air electrode side, a medium for applying inner pressure is poured from a pouring port 63 installed in at least one metallic plate 62 of the laminated plate material, and the metallic separator on the fuel electrode side having a shape similar to the shape of the recessed part for the fuel electrode and the metallic separator on the air electrode side having a shape similar to the shape of the recessed part for the air electrode are integrally molded.
