Abstract
A rubber composition comprising (A) an alkenyl-containing organopolysiloxane, (B) a silicone resinous copolymer, (C) an organohydrogenpolysiloxane, (D) fumed silica having a BET specific surface area of 50-400 m/g, (E) carbon powder having a BET specific surface area of 30-150 m/g, and (F) an addition reaction catalyst cures into a product which is useful as a separator seal in PEFCs. The rubber has a reduced compression set even in an acidic atmosphere or in contact with LLC, and the rubber itself has strength and good adhesion to separator substrates. The separator provides excellent seal performance over a long term.
