The molten carbonate fuel cell has conspicuous features and high potential in being used as an energy converter of various fuels to electricity and heat. However, the MCFC which use strongly corrosive molten carbonate at 650℃ have many problem. Systematic investigation on corrosion behavior of Fe/20Cr/Ti has been done in (62+38)mol % (Li+K) CO3 melt at 923K by using. steady state polarization and electrochemical impedance spectroscopy method. It found that the corrosion current of these Febased alloys decreased with increasing Ti content, and this attribute to the formation of LiCrO2 layer at the surface.
