Conductive composition for solid polymer type fuel cell separator, solid polymer type fuel cell separator, solid polymer type fuel cell and solid polymer type fuel cell system using the separator |
摘要 |
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; and 2) a thermoplastic resin and/or a thermosetting resin, 3) the graphite particles having an average particle diameter D1 of 55 to 65 mum, 4) the melt viscosity being 1x10<SUP>2 </SUP>to 5x10<SUP>3 </SUP>Pa.s at 320° C., and 5) 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.
