The Investigation of Perovskite LaCo<sub>0.6</sub>Ni<sub>0.4</sub>O<sub>3-δ</sub> as Cathode Interface Contact Material for Intermediate Temperature Solid Oxide Fuel Cells

Abstract

The goal of this study is to identify LaCo0.6Ni0.4O3-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.
