ABSTRACT:
1. A conductive composition for a polymer electrolyte fuel cell separator comprising:1) a conductive component composed of graphite particles and optionally fine graphite particles; and2) a thermoplastic resin and/or a thermosetting resin,3) the graphite particles having an average particle diameter D1 of 55 to 65 μm,4) the melt viscosity being 1×102to 5×103Pa·s at 320° C., and5) the weight ratio of (the graphite particles and optionally the fine graphite particles)/(the thermoplastic resin and/or the thermosetting resin) being 95/5 to 75/25.
