    摘要: A method for manufacturing a fuel cell separator, provided with: (A) a press molding step in which a composition containing a graphite powder, an epoxy resin, and a phenol resin is press-molded 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 step for roughening the entirety of both surfaces of the molded article; (C) a gasket formation step for 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) a laser irradiation step for 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) a hydrophilization step for rendering the entire gas channel surface hydrophilic. This manufacturing method makes it possible to obtain a separator having excellent sealing properties in which a decrease in hydrophilic properties due to gasket lamination is prevented and excellent adhesion is obtained between the gasket and the separator.

    摘要: A method for manufacturing a substrate-integrated gasket that does not require air vents to be provided extending from a cavity in a mold and thus does not require a post-process for removing flash that forms in the air vents comprises: a coating step of coating a front surface of a substrate (1) with an adhesive in a prescribed pattern corresponding to an extended shape of a gasket to be molded; and a step of filling and curing an uncured molding material in a cavity (40) that is defined between the substrate (1) and an inner surface of a mold (10) by mounting and clamping the substrate (1) inside the mold. The coating step includes forming a main adhesive coated region (31) extending along an extending direction of the cavity (40), partial adhesive coated regions (32) capable of closely contacting the mold (10) outside the cavity (40), and non-adhesive coated regions (33) extending from a position outside the cavity (40) to a position inside the cavity (40).
