PURPOSE:To obtain a separator material for fuel cell having superior corrosion resistance to fused carbonate, by constituting the material by the use of an Fe-base alloy containing specific compositional amounts of C, Si, Mn, Ni, Cr, and Al. CONSTITUTION:The separator material for fuel cell is composed of an Fe-base alloy containing, by weight, <=0.15% C,<=1% Si, <=2% Mn, 15-35% Ni, 15-35% Cr, and 1-2% Al and has superior corrosion resistance to fused carbonate. Further, the above-Fe-base alloy may contain minimum amounts of inevitable impurities. The above separator material is particularly suitable for separator for fused carbonate fuel cell. Moreover, when used for current collector, etc., the above Fe-base alloy can prolong the service life of a plant. |
