Abstract:

The goal of this study is to identify LaCo_0.6Ni_0.4O_3-δ (LCN) as reliable cathode contact material for intermediate temperature solid oxide fuel cells (SOFC). LCN was prepared through the polymeric steric entrapment precursor route and calcined at 800 °C which shows single perovskite phase. Area specific resistance (ASR) of LCN was measured at 750 °C. The investigation shows that the ASR can be maintained about 50 mΩ·cm² for 100 hours operation, and presented ASR stability within 10th thermal cycles. The excellent performance of LCN is attributed to good interface adhesion between LCN and interconnect alloy.
