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.

立方钙钛矿型Sm0.3Sr0.7Nb0.08Co0.92O3-δ作为中温固体氧化物燃料电池的新型阴极材料。

立方钙钛矿型Sm0.3Sr0.7Nb0.08Co0.92O3-δ(SSNC)在600°C下表现出优异的氧还原反应(ORR)活性,这归因于氧空位的高浓度和高迁移率,这是由于平均氧含量低而导致的室温下SSNC中的钴价和立方结构。
