Abstract

Abstract:

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.

Key words: fuel cell, electrochemical performance, hydrogen energy, perovskite, clean energy, oxygen vacancy, proton conduction
