Abstract

Cubic perovskite-type Sm_0.3Sr_0.7Nb_0.08Co_0.92O_3−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.
