Abstract

A method of manufacturing a metal separator for a fuel cell includes providing an opening in a metal plate which is to be a part of the metal separator for the fuel cell, integrally molding a sealing member on both sides of an outer peripheral edge of the metal plate to cover the opening, and trimming the sealing member to remove a covering portion of the sealing member that covers the opening and to provide a fluid communication hole, at least one of a fuel gas, an oxidant gas, and a cooling medium being to pass through the fluid communication hole in the fuel cell.
