Abstract: Medium-and high-temperature proton conductors with perovskite structure have got much attention due to their good application prospects. Some proton conductors were introduced, which have been mostly studied nowadays, and the structures, characteristics and electric conduction mechanism of perovskite-type proton conductors were described. The chemical stability, strength and conductivity of all kinds of proton conductors were compared. The methods of preparation and characterization of proton conductors were also described. The effect of different doping elements on the proton conductivity and the stability of the perovskite-type oxides were analyzed, and the methods for improving the properties of proton conductors were summarized. The latest research results both at home and abroad are introduced. The focal points of research were presented as improving the traditional proton conductors, developing new type proton conductors and improving the preparation technology, in order to improve the stability and conductivity and expand the work temperature range of proton conductors.
