Abstract:
1. A fuel cell separator formed from a hydrothermally resistant electroconductive cured product which has a Tg of 160° C. or more, a bending strength of 30 MPa or more in accordance with JIS K 6911, and a volume resistivity of 2×10 −2 Ωcm or less, obtained by curing a curable composition comprising: (A) a hydrocarbon compound having a plurality of carbon-carbon double bonds, (B) an electroconductive carbonaceous material selected from the group consisting of, or a combination of at least two kinds of: natural graphite, artificial graphite, expanded graphite, carbon black, a pitch-type carbon fiber obtained from heavy oil, by-product oil or coal tar, a PAN-type carbon fiber obtained from polyacrylonitrile, and vapor grown carbon fiber having a fiber diameter of 0.1 to 5 μm, and (C) at least one curing initiator selected from the group consisting of organic peroxides and azo compounds, wherein the hydrocarbon compound (A) having a plurality of carbon-carbon double bonds is a polymer having a carbon-carbon double bond in a side chain thereof, wherein at least one flow channel for a gas is formed on one side or both sides thereof.
