Abstract Herein, we report enhancement of the electrochemical performance of the Ba0.5Sr0.5Co0.8Fe0.2O3−δ/Ce0.85Sm0.15O2−δ (BSCF/SDC) composite cathode for intermediate temperature solid oxide fuel cells by improving the ionic conductivity of SDC through addition of CuO. Furthermore, the effect of the sintering temperature on the crystal structures, surface morphology, and electrochemical properties of the BSCF/SDC–CuO cathode was investigated. Three sintering temperatures were investigated (900, 950, and 1000 °C). The findings showed that raising the SDC ionic conductivity and a sintering temperature of 950 °C were the optimal conditions for improving the performance of the composite cathode.

摘要 在此，我们报告了通过提高离子电导率来增强 Ba0.5Sr0.5Co0.8Fe0.2O3−δ/Ce0.85Sm0.15O2−δ (BSCF/SDC) 复合阴极的电化学性能，用于中温固体氧化物燃料电池SDC 通过添加 CuO。此外，研究了烧结温度对 BSCF/SDC-CuO 阴极的晶体结构、表面形貌和电化学性能的影响。研究了三种烧结温度（900、950 和 1000 °C）。结果表明，提高SDC离子电导率和950°C的烧结温度是提高复合正极性能的最佳条件。
