    • In order to attain excellent electrical conductivity and molding processability, a fuel cell separator to be produced by performing press molding on a preform in which expanded graphite is used as the main raw material is improved so that the preform is produced by a papermaking method, whereby the characteristics of the mechanical strength, the flexibility, and the gas impermeability are improved, and the moldability is made excellent so that a light and compact configuration that is preferred in the automobile use or the like can be realized. In a fuel cell separator which is to be produced by performing press molding on a preform 14 that is formed into a plate-like shape, with a molding die, therefore, the preform 14 is configured into a sandwich structure where a first sheet 14A made by impregnating a sheet-like member with a phenol resin, the sheet-like member being obtained by a papermaking process using a raw material in which a fibrous filler is added to expanded graphite, is interposed between a pair of second sheets 14B in which a phenol resin is applied to graphite.
    • 为了实现良好的导电性和成型加工性,对以膨胀石墨为主要原料的预成型体进行加压成型而制造的燃料电池用隔膜改良,由此通过造纸法制造预成型体, 机械强度,柔软性,不透气性的特性提高,成型性优异,能够实现汽车用等优选的轻量且紧凑的结构。 因此,在通过在成型为板状的预成型件14上利用成型模具进行加压成型而制造的燃料电池用隔离件中,预成型件14被构成为夹层结构,其中第一片材14A 通过使用酚醛树脂浸渍片状构件,通过使用其中向膨胀石墨添加了纤维状填料的原材料的造纸工艺获得的片状构件插入在一对第二片14B之间,在该对第二片14B中, 酚醛树脂应用于石墨。
