PURPOSE:To improve corrosion resistance to fused carbonate, by specifying the additive quantity of Al in an Fe-Ni-Cr alloy and adding Y in combination. CONSTITUTION:An alloy for fused carbonate fuel cell has a composition consisting of <=0.15% C, <=1% Si, <=2% Mn, 15-35% Ni, 15-35% Cr, 0.1-0.9% Al, 0.5% Y, and the balance Fe with inevitable impurities. Y is added in combination with Al. By this composition, a material having superior corrosion resistance to fused carbonate can be provided. Accordingly, when this alloy is used for separators, current collectors, etc., for fused carbonate fuel cell, the service life of a plant can be prolonged. |
