A FUEL CELL SEPARATOR, A FUEL CELL USING THE FUEL CELL SEPARATOR, AND A METHOD FOR MAKING THE FUEL CELL SEPARATOR

摘要

A fuel cell separator including (a) about 100 parts by weight of graphitized meso-carbon microbeads, (b) about to 35 parts by weight of one of a thermosetting resin and a thermoplastic resin, and (c) about 1 to 40 parts by weight of at least one carbonaceous material selected from the group consisting of graphite powder, carbon black, and fine carbon fibers. The fuel cell separator exhibits low electrical resistivity, low volume resistivity, superior gas impermeability, and superior dimensional accuracy without a graphitizing treatment after molding. A fuel cell using the fuel cell separators can be produced while saving energy using a simplified facility and has superior generation efficiency.
