CARBONACEOUS COMPOSITE MATERIAL, PROCESS FOR PRODUCTION THEREOF, FUEL CELL SEPARATOR AND POLYMER ELECTROLYTE FUEL CELL

摘要

A carbonaceous composite material molded from a carbonaceous composite compound composed mainly of graphite, a thermosetting resin, and a fibrous base material, wherein molding is carried out in such a way that said fibrous base material is oriented in said carbonaceous composite material; a process for producing said carbonaceous composite material; a fuel cell separator having said carbonaceous composite material as a component; and a polymer electrolyte fuel cell. The carbonaceous composite material can be produced by injection molding, transfer molding or extrusion molding without difficulties encountered in the past. It has high strength, with a minimum amount of warpage. It contributes to productivity.
