ABSTRACT:
There is provided a conductive curable resin composition comprising (A) a curable resin composition comprising an elastomer with a Mooney viscosity (ML1+4(100° C.)) of 25 or greater at 2-80 wt % and (B) a carbon material, with a weight ratio of component (A) to component (B) of 70-5:30-95. The curable resin composition of component (A) preferably comprises (A1) an elastomer at 80-2 wt %, (A2) a radical reactive resin at 20-98 wt % and (A3) an organic peroxide at 0.2-10 parts by weight to 100 parts by weight of (A1+A2). Also provided are a process for production of a conductive cured resin by shaping and curing of the conductive curable resin composition, and a fuel cell separator, an assembly for a cell, an electrode or a heat releasing plate, obtained thereby.
