Abstract

Perovskite oxide Sr2Fe1.3Cu0.2Mo0.5O6-δ (SFCM) is prepared and evaluated as a novel cathode material for solid oxide electrolytic cells (SOECs). At 750 °C, the interfacial polarization resistance value decreased from 1.834 to 1.125 Ω cm2 and the SFCM cathode exhibited excellent stability for 100 h, without any significant attenuation, at an electrolytic voltage of 1.5 V.

摘要

制备了钙钛矿氧化物Sr2Fe1.3Cu0.2Mo0.5O6-δ（SFCM），并将其作为固体氧化物电解池（SOEC）的新型阴极材料进行评估。在750°C下，界面极化电阻值从1.834降低到1.125Ω·cm2，并且SFCM阴极在1.5V的电解电压下表现出优异的稳定性，持续100小时无明显衰减。
