Abstract

En 中文
• The Ce0.8Sm0.2O1.9 (SDC) powders with different morphology are synthesized by sol-gel method via varying calcining temperatures. • The morphology characteristic of SDC powders has an important influence on the electrochemical performance of resultant GBCO-SDC (GS) composite cathodes. • The GS1000 composite cathode displays excellent ORR catalytic activity with a low area-specific resistance of 0.048 Ω cm2 at 700 °C.
