<p>A conductive composition or the like useful for the production of a solid polymer type fuel cell separator. A solid polymer type fuel cell separator, which is currently made by forming grooves by cutting in a carbonaceous or graphite flat plate, poses a high-cost problem. A proposed method of making the separator by injection-molding or compression-molding a resin composition containing a conductive agent raises a problem of difficulty with which a molded product, that has a thickness of up to 2 mm and even portions further reduced in thickness by the presence of irregular portions and grooves, must be uniformly molded. The above problem has been resolved by using a composition, for the above composition, containing graphite particles 55-65 νm in average diameter and thermoplastic resin and/or thermosetting resin at a weight ratio of 95/5 to 75/25 and having a melt viscosity at 320°C of 100-5000 Pa.s.</p> |
