Abstract

See full text

A method for manufacturing a fuel cell separator includes heating a sheet, pressing the sheet using a first die, thereby forming the sheet so as to have a predetermined thickness, cooling, together with the first die, the sheet that has been formed so as to have the predetermined thickness, and pressing the sheet that has undergone the cooling using a second die, thereby forming a gas passage in the sheet. In the sheet, a content of a thermoplastic resin is greater than or equal to 20 weight percent and less than or equal to 30 weight percent and a content of the carbon material particles is greater than or equal to 70 weight percent and less than or equal to 80 weight percent. The heating the sheet includes heating the sheet to a temperature that is higher than a melting point of the thermoplastic resin.
