摘　　要：简要介绍了一类高性能聚合物—聚苯并咪唑的制备方法及其在高温质子交换膜燃料电池中的应用研究进展;阐述了磷酸掺杂聚苯并咪唑膜的质子传导机理,探讨了磷酸掺杂率对聚苯并咪唑膜的力学强度和质子导电率等性能的影响规律;并对今后磷酸掺杂聚苯并咪唑质子交换膜研究领域需要解决的关键问题进行了讨论。A class of high performance polymers, polybenz^midazoles, were briefly introduced including their synthe- sis,characterization and applications in high temperature proton exchange membrane fuel cells. The proton conducting mechanism of the phosphoric acid-doped membranes was elucidated. The effects of phosphoric acid doping level on mechani- cal strength and proton conductivity of the membranes were discussed. Finally, the key problems associated with the mem- branes which was ned to be solved in the future were also discussed.
