Abstract:
Cubic perovskite-type Sm0.3Sr0.7Nb0.08Co0.92O3-δ (SSNC) demonstrated excellent oxygen reduction reaction (ORR) activity at 600 °C due to a high concentration and high mobility of oxygen vacancies, which were derived from the low average cobalt valence and cubic structure in SSNC at room temperature.
