摘　　要：双极板是质子交换膜燃料电池(PEMFC)的核心组件之一,其质量的好坏直接决定电池堆输出功率的大小和使用寿命的长短.金属双极板因具有优异的力学性能和导电性能,成为当前PEMFC双极板研究中关注的焦点.但是,纯金属双极板在质子交换膜燃料电池环境中易受腐蚀,金属板腐蚀后,释放出可能毒害催化剂的金属离子,或形成可增加界面接触电阻的致密氧化膜,影响燃料电池的输出功率和使用寿命,对金属双极板进行表面改性可以有效解决上述问题.本文首先概述了双极板的种类、优缺点;然后,系统总结了金属双极板表面改性涂层的制备方法、性能与最新研究进展,主要涉及金属基涂层、碳基涂层和导电聚合物涂层;最后分析了改性涂层国产商业化面临的挑战及国内外产业化现状,从成本和寿命出发展望了金属双极板表面改性的发展方向.Bipolar plates are the core components of proton exchange membrane fuel cells(PEMFC), and their quality directly determines the output power and service life of the battery stack. Metal bipolar plates have attracted intensive attention and become the research focus of bipolar plates in PEMFC due to their excellent mechanical and electrical performances. Unfortunately, bare metal bipolar plates are prone to corrosion in PEMFC. After the corrosion of metal bipolar plates, the released metal ions could poison the catalyst, and the formed dense oxide film could increase the interface contact resistance, affecting the output power and service life of the PEMFC. Surface modification of metal bipolar plates can effectively tackle the aforementioned problems. In this review, firstly, the types, merits and disadvantages of bipolar plates are introduced. Subsequently, preparation methods, performances and the latest research progress of surface modified coatings, such as metallized coating, carbon based coating and conducting polymer coating, for metal bipolar plates are systematically summarized. Finally, the commercialization challenges of modified coatings in China and current industrialization situation at home and abroad are analyzed. Furthermore, the development direction of surface modification of metal bipolar plates is prospected from the point of view of cost and service life.
