Abstract
An electroconductive resin composition, which comprises a thermosetting resin as a matrix and 40 to 90% by weight, on the basis of the composition, of carbon fibers and graphite as fillers, has a high electroconductivity and is suitable for use as a molding material for fuel cell separators. By using a molding material comprising phenol resin as a matrix and at least one kind of carbon fibers and graphite being coated by an electroconductive metal and molding fuel cell separators from the molding material, followed by post-curing at 130 to 300.degree. C., fuel cell separators with a stable power generation capacity can be obtained.
