Traditional composite cathode was usually mixed with cathode materials and BaZr0.1Ce0.7Y0.2O3-delta (BZCY) to obtain thermal and chemical compatibility with proton-conducting electrolyte. Considering the poor chemical stability of BZCY in wet atmosphere, three different composite cathodes of La0.6Sr0.4Co0.2Fe0.8O3+delta (LSCF)-BZCY, LSCF-Sm0.2Ce0.8O2-delta (SCO), LSCF-La2Ce2O7+delta (LCO) were fabricated and systematically researched. Due to the high chemical stability and triple conductivity, the single cell with cathode of LSCF-LCO presented a better cell performance of 1020 mW.cm(-2) at 700...
