Abstract
A separator for fuel cell, obtained by molding a resin composition comprising 100 parts by weight of a graphite, 15 to 30 parts by weight of a bisphenol A type epoxy resin, 2 to 4 parts by weight of a phenolic resin, and 1 to 10 parts by weight of a polycarbodiimide resin, which, unlike the prior art, is superior in moldability, electrical conductivity and mechanical strength and causes no cracking during molding even when made in a small thickness.
