摘要/Abstract

摘要： 固体氧化物燃料电池(SOFC)是一种可以将燃料中的化学能直接转化为电能的发电装置,具有燃料选择灵活、效率高、环境友好等优点。基于SOFC运行成本和长期稳定性的要求,降低工作温度已成为当前研究的热点。传统阴极较低的催化活性制约了SOFC的技术发展,因此开发具有良好催化性能的阴极材料至关重要。大量的研究表明,铋离子的掺杂能够有效提高材料的电导率和氧催化活性。从铋离子掺杂的角度出发,综述了铋离子掺杂对阴极材料的制备、结构、电导率和电化学性能的影响,并对掺铋SOFC阴极材料未来的发展趋势进行了展望。

Abstract: Solid oxide fuel cell (SOFC) is one of power generation device which can directly convert chemical energy in fuel into electric energy, with the advantages of flexible fuel selection, high efficiency, and environmental friendliness. Reducing operating temperature has become a hot topic in current research to fulfill the requirement of the running cost and long-term stable operation of solid oxide fuel cell systems. The low catalytic activity of traditional SOFC cathode materials restricts the development of SOFC technology. Therefore, it is very important to develop cathode materials with good catalytic activity. Many studies have shown that bismuth ion doping in materials can effectively improve the conductivity and oxygen catalytic activity. Bismuth ions have unique electronic structure. From the perspective of bismuth ion doping, the effect of bismuth ion doping on the preparation, structure, conductivity and electrochemical performance of cathode materials was reviewed, and development trend of bismuth ion SOFC cathode materials was prospected.

Key words: solid oxide fuel cell, cathode material, bismuth doping
