A high performance composite cathode with enhanced CO2 resistance for low and intermediate-temperature solid oxide fuel cells

CO2-resistant perovskite cathode has a significant role in solid oxide fuel cell (SOFC) application particularly for operation in an air atmosphere contains higher than normal amount of CO2 such as in single-chamber SOFC (SC-SOFC). This work features a systematic study of the electrochemical performance of SrCo0.8Nb0.1Ta0.1O3-δ (SCNT)-Ce0.9Gd0.1O2−δ (GDC) composite cathode under CO2 exposure for SOFC operation in low-temperature (LT, 500 °C and...
