【 摘 要 】

An overview of intermediate temperature (100–300 °C) proton conducting membrane electrolyte materials for fuel cells is presented in this review. The fuel cells operated in intermediate temperature range could enhance the electrochemical kinetics, simplify water management, and improve impurities resistance. Polyfluorosulfonic acid polymer membrane represented by Nafion, and non-fluorinated arylene polymer membranes represented by polybenzimidazole are the two most widely polymer electrolyte membranes for intermediate temperature membrane. The structure regulation and fillers addition are two effective ways to maintain the conductivity and mechanical properties of membranes at intermediate temperature. Moreover, heteropolyacids, metal pyrophosphates and inorganic membranes also have attracted widespread attention when they operate at intermediate temperature.
