Abstract
FeCr alloy, characterized with high oxidation temperature and electrical resistance, is a potential material for solid oxide fuel cell (SOFC) interconnects. Preparation processes of FeCr alloy were optimized via high energy ball-milling (HEBM), spark plasma sintering (SPS) and lanthanum ion implantation in order to develop an efficiently specimen with low oxide scale growth and electrical resistivity. The commercially available ferritic steel was chosen as a comparison of another high-Cr ferritic alloy. They were evaluated at 900 oC in the air corresponding to the environment of SOFC. The area specific resistance (ASR) of oxide scales was measured. The results show that the developed FeCr alloy has demonstrated a low ASR value after 100 hours, indicating the long-term stability of oxide layer, compared to the commercially available alloy.
