Abstract

Perovskite-type Nd0.75Sr0.25Co0.8Fe0.2O3-δ (NSCF) has shown excellent oxygen reduction reaction (ORR) properties (an area specific polarization resistance of 0.1 Ω cm2 at 700 °C) as a composite cathode (30 wt% La0.8Sr0.2Ga0.8Mg0.2O3-δ (LSGM)) with remarkable chemical stability under CO2. The mechanism for the ORR was established employing pO2 and temperature dependent studies.

摘要

钙钛矿型 Nd0.75Sr0.25Co0.8Fe0.2O3-δ（NSCF）作为复合阴极（30wt%La0.8Sr0.2Ga0.8Mg0.2O3-δ（LSGM））与 CO2 下具有显著化学稳定性，显示出优异的氧还原反应（ORR）性能（700°C 时的比面积极化电阻为 0.1 Ω cm2）。采用 pO2 和温度依赖研究确定了 ORR 的机制。
