PROBLEM TO BE SOLVED: To effectively remove the distortion or residual stress of a separator in almost the same condition as the condition, in which the separator is assembled in a fuel cell, and enhance sealing performance with separators between cells of the fuel cell, by reforming by fastening with a fastening member, when the separator is cooled. SOLUTION: This annealing treatment method of the separator for the fuel cell is composed of a process, in which a plurality of separators for the fuel cell formed by compression molding a mixture of carbon and thermosetting resin are arranged and interposed between a pair of reforming plates; a process putting the separators together with the reforming plates into a heating furnace; and a reforming process reforming the separators by fastening with a bolt and a nut at the specified load and for the specified time, during cooling after being taken out of the heating furnace. |
