Alloys of the intermetallic material based on Fe40Al60 and the alloys formed with addition of Ag constitute a new alternative to improve the problems of corrosion resistance and electrical conductivity. The electrochemical characterization was employed to evaluate the corrosion resistance of the materials for being used as bipolar plates in molten carbonate fuel cells (MCFC). These characterizations were done under similar conditions as the working environment of the molten carbonate fuel cell (MCFC). The working environment of the standard molten carbonate fuel cell was simulated by the use of molten salts of 62 mol.% Li2CO3 and 38 mol.% K2CO3 at the temperature of 650 ºC. Alloys included Fe40Al60 with additions of 1, 3 and 5 weight % of Ag. The results obtained indicate that this material is promising for its use as bipolar plates in MCFC.
