RESIN COMPOSITION FOR DENSE FUEL CELL SEPARATORS

The present invention is a resin composition for dense fuel cell separators, which contains a graphite powder and an epoxy resin component that contains a base material, a curing agent and a curing accelerator, and wherein: the graphite powder has a spring back of 20-70% and an average particle diameter d50 of 30-100 μm; and the curing accelerator is an imidazole compound that has an aryl group in the 2-position. This resin composition for dense fuel cell separators enables the achievement of a dense separator for fuel cells, which satisfies a predetermined performance even in cases where the separator is compression molded in a short time that is less than 10 seconds.
