介绍了燃料电池的种类和特点,尤其是质子交换膜燃料电池(PEMFC)的技术优势、应用领域和商业化面临的主要技术障碍.简述了膜电极组件(MEA)的结构及质子交换膜(PEM)在其中的作用,指出PEM表面图案化是提升燃料电池在高温低湿条件下综合性能的一个重要方法.总结了近年来PEM表面图案化的基本策略,包括模板铸膜法、模板压印法、辐照修饰法、表面打印和微观相分离法等,并探讨了各自的优缺点.讨论了图案化存在的问题和面临的挑战,并对未来发展方向进行了展望.
Abstract
The types and characteristics of fuel cells were introduced,especially the technical advantages,application fields,and main technical obstacles faced by proton exchange membrane fuel cells(PEMFC)in commercialization.The structure of membrane electrode assembly and the role of proton exchange membrane(PEM)in it were briefly described.It is pointed out that surface patterning of PEM is an important method to improve the comprehensive performance of fuel cells under high temperature and low humidity conditions.The basic strategies for surface patterning of PEM in recent years were summarized,including template casting method,template imprinting method,irradiation modification method,surface printing and micro phase separation method,along with their respective advantages and disadvantages.The existing problems and challenges of PEM surface patterning were discussed,and the future development directions were prospected.
