Heteropoly acids （HPAs） solid high-proton conductors have received increasing attention over the last few years owing to their applications in fuel cells, sensors and electrochemical chromogenie devices etc. The present paper summarizes and reviews the current development in the area of the eonduetivities of HPAs, HPAs-inorganic matrix composite materials, HPAs-organic hybrid materials and HPAs-multiple composite materials. The conductivities of these materials are listed in the corresponding tables. Some laws of proton conductivity are summarized. By loading various weight percentages of HPAs onto different solid matrixs, the stability and mechanical ductility of solid proton conducting materials can be increased. The composite materials combine the high thermal and structural stability of matrixs with outstanding conductivity of HPAs, which place them among one of the most promising solid proton conductors. The higher the humidity is and the more the doping amount of HPAs is, the higher the conductivities of the composite materials are. The applications of HPAs in proton exchange membrane fuel cells are described in detail. The future development and research trends of HPAs solid high-proton conductors are prospected.
