<P>PROBLEM TO BE SOLVED: To provide a material composition for a fuel cell separator high in hardening speed and excelling in flowability; and to provide a fuel cell separator formed by molding the composition, having low electric resistance and excelling in gas impermeability. <P>SOLUTION: This material composition for a fuel cell separator contains an epoxy resin represented by formula (1), a hardening agent, and graphite. This fuel cell separator is formed by molding the composition. In formula (1), R is hydrogen, a straight-chain-like or branch-like alkyl group having a carbon atom number of 1-4, a phenyl group or a naphthyl group; Gr is a glycidyl group; and n is 0 to 10. <P>COPYRIGHT: (C)2007,JPO&INPIT |
