PURPOSE:To offer a high corrosion resistant steel sheet for a molten carbonate type fuel cell separator. CONSTITUTION:The compsn. of an alustenitic stainless steel contg., by weight, <=0.1% carbon, <=1% silicon, <=35% manganese, 5 to 26% chromium, <=20% nickel and the balance iron with inevitable impurities is regulated to a one in which one side is coated with pure nickel or pure copper or an alloy contg. one of nickel and copper by >=80%. In molten calbonate of 700 deg.C, its corrosion amt. is one several compared to that of a 25 chromium 20 nickel steel as the conventional material.
