Abstract:
A method for manufacturing a fuel cell separator, provided with: (A) a press molding a composition containing a graphite powder, an epoxy resin, and a phenol resin under heat in a mold to obtain a molded article having a groove that serves as a gas channel on one or both surfaces; (B) a roughening the entirety of both surfaces of the molded article; (C) forming a gasket on the peripheral edge part of the gas channel surface having the groove that serves as a gas channel in the roughened molded article; (D) irradiating the portion of the gas channel surface where the gasket is not formed, and at least the peak part and the bottom part of the groove that serves as a gas channel, with infrared laser light; and (E) rendering the entire gas channel surface hydrophilic. Decrease in hydrophilic properties due to gasket lamination is prevented.

Claim (Index 1):
A method for manufacturing a fuel cell separator, comprising:\n (A) a press molding step for press-molding a composition containing a graphite powder, an epoxy resin, and a phenol resin under heat in a mold to obtain a molded article having a groove serving as a gas channel on one or both surfaces: (B) a roughening step for roughening the entire both surfaces of the molded article; (C) a gasket formation step for forming a gasket on a peripheral edge part of a gas channel surface having the groove serving as a gas channel in the roughened molded article; (D) a laser irradiation step for irradiating a portion of the gas channel surface where the gasket is not formed, and at least a bottom part and a peak part of the groove serving as a gas channel, with infrared laser light; and (E) a hydrophilization step for hydrophilizing the entire gas channel surface.
