摘要
质子导体固体氧化物燃料电池(H-SOFC)是一种高效清洁的能源转换装置,可直接将燃料气体转化为电能。虽然传统燃料电池的制备技术日益成熟,但较高的工作温度极大地限制了它的发展。随着燃料电池的工作温度不断降低,中温质子导体燃料电池受到研究者的广泛关注。H-SOFC继承了传统燃料电池全固态及燃料使用灵活等优点,且表现出了优异的电化学性能。但低温环境下阴极反应的动力学缓慢及质子传导率的降低使得燃料电池的电化学性能大大降低。介绍了中温质子导体燃料电池的结构及工作原理,综述了近年来H-SOFC的电解质、阳极和阴极的发展趋势,分析了目前H-SOFC发展面临的挑战。
Proton-conducting solid oxide fuel cells(H-SOFC)are efficient and clean energy conversion devices which can directly convert fuel gas into electric power.Although the preparation technology of traditional fuel cells is mature,its development is dramatically limited by high working temperatures.As the working temperature of fuel cells get decline,intermediate-temperature proton-conducting fuel cells attract extensive attention of researchers.H-SOFC are of the advantages of traditional fuel cells such as all-solid state and flexible application,and also show excellent electrochemical performances.However,the slow kinetics of the cathode reaction and the decrease of proton conductivity in low temperature greatly detriment their electrochemical performance.Based on the understanding on the structure and working principle of intermediate-temperature proton-conducting fuel cells,the developments of their electrolytes,anodes and cathodes in recent years are reviewed and the challenges in front of the cells are analyzed.
