摘　　要：燃料电池因具有能源转换效率高、近零污染、低噪音等优点受到广泛关注。聚合物电解质膜作为燃料电池的重要组成部件之一,其性能优劣决定了电池的实际表现。为解决聚合物电解质膜在稳定性及离子传导率方面存在的不足,无机纳米材料掺杂作为常规的改性手段应用到聚合物电解质膜材料中。近年来,石墨相氮化碳(g-C_(3)N_4)因其独特的结构特征和优秀的物化性能,被广泛应用于聚合物电解质膜材料的制备和改性。本文主要综述了g-C_(3)N_4的结构和性质,总结了g-C_(3)N_4基复合膜的制备方法,重点对目前g-C_(3)N_4在聚合物电解质膜中的研究和应用情况进行了综述,展示了其在聚合物电解质膜改性方面的重要成果,并对其在该领域未来的发展做出展望。Fuel cells have attracted wide attention due to the high energy conversion efficiency,near-zero pollution and low noise.Polymer electrolyte membrane(PEM)is an important component of fuel cells,its performance determines the practical output of fuel cells.To address the shortcomings of PEMs in terms of stability and ionic conductivity,inorganic nanomaterial doping is applied to PEMs as a conventional modification method.In recent years,graphitic carbon nitride(g-C_(3)N_(4))has been widely used in the preparation and modification of PEMs due to its unique structural characteristics and excellent physic-chemical properties.This review mainly describes the structural properties of g-C_(3)N_(4),summarizes the typical preparation methods of g-C_(3)N_(4)-based composite PEMs,focuses on the current research and application of g-C_(3)N_(4),demonstrates its important achievements in the modification aspect,and gives an outlook on its future development in PEMs.
