Abstract: The corrosion behavior of the separator in molten carbonate fuel cells was studied. X ray diffraction (XRD) scanning electron micrographs (SEM) and ion analysis were employed to study the hot corrosion products. It is shown that the chief components of the corrosion products included NiFe2O4, LiFeO2, NiCr2O4 etc. Meanwhile, through the measurement of the corrosion dynamics of the bipolar boards as well as the anode and the preliminary discussion of the corrosion mechanism, it is known that their hot corrosion rate is relatively fast, corrosion layers are relatively loose and there is possibility that they have co corrosion effect.

Key words: molten carbonate fuel cell, separator, corrosion
