Abstract

The use of a metallic rather than a ceramic interconnector has become a popular choice in the SOFC technology because of key advantages in terms of electronic and heat conductivity, as well as workability characteristics. However, corrosion problems still remain to be solved with metallic interconnectors, particularly in high temperature applications (HT-SOFC, 800°C and above). High Cr ferritic stainless steels with suitable ceramic protective layers are therefore widely used for their good property balance, including corrosion resistance in HT-SOFC systems. However, recent trends in reducing operational temperatures below 800°C could make it attractive using more cost effective alternatives such as low Cr grades of ferritic stainless steel. Here, we report preliminary results on the long-term corrosion behaviour of a commercial ferritic stainless steel containing 13Cr % (SS405), at 700°C under simulated cathode conditions.
