<P>PROBLEM TO BE SOLVED: To provide a separator for a fuel cell, which can stabilize conductivity in the surface direction, and to provide its manufacturing method. <P>SOLUTION: The separator for the fuel cell is formed by heating powder molding of a molding material containing powdery conductive material and thermoplastic resin, the surface layer of the molded separator is removed by sandblast, and the separator whose surface layer is removed is cleaned with water. Since the surface layer of the separator is physically precisely removed by sandblast and then dust or the like caused due to sandblast is removed by the cleaning with water, conductivity in the surface direction of the separator can be stabilized independent of the presence or absence of grooves on the separator surface. <P>COPYRIGHT: (C)2009,JPO&INPIT |
