Heat-resistant ferritic alloys were investigated for use as a SOFC separator material in order to reduce the difference in thermal expansion between the electrolyte and separator. The heat resistance of ferritic alloys was improved by adding a small amount of lanthanum, making it possible to use them as a SOFC separator. The thermal cycle characteristics were improved in a 50 mm × 50 mm single cell using this ferritic alloy in comparison with a cell using an Ni-based alloy. The single cell was operated for about 7000 h. Degradation of the cell performance was apparently mainly caused by gas leakage.
