摘　　要：中低温(600～800℃)固体氧化物燃料电池是目前研究的主流.降低工作温度虽然能够解决材料选择、热应力、腐蚀等一系列问题,但是导致了阴极性能和阴极效率下降.复合阴极在某种程度上可以改善低温下阴极性能恶化的情况,降低过电位和极化电阻、界面电阻等.介绍了复合阴极的研究理论和研究方法,以及为解决这些问题所进行的阴极复合研究的现状,包括阴极材料与电解质、贵金属材料复合的研究现状,提出了今后的研究方向及应解决的问题.Intermediate and low-temperature solid oxide fuel cell is a mainstream of researches in this field currently. Lowering operation temperature can solve a serial of problems, such as material selection, thermal stress and material corrosion. Unfortunately, it makes a degradation of the performance and cathode efficiency. Researches prove that composite cathode can solve the problems and improve the performance and efficiency at lower temperature to a certain extend. It decreases the overpotential, polarization resistance and interfacial resistance, etc. The theoretical foundation, research means and present tendency of composite cathodes of electrolyte-cathode and noble metal-cathode were introduced. The problems that should be solved and future development were presented.
