【摘要】 质子交换膜是氢燃料电池中的关键部件之一,然而它的性能却不能完全满足人们的需求,因此对质子交换膜的改性研究一直在拓展、深入。介绍了不同种类的质子交换膜,即全氟磺酸、部分氟化、无氟、复合质子交换膜的研究情况,综述了质子交换膜材料的改性方法以及高温、阻醇型质子交换膜的研究进展,指出了当前研究的特点和问题,提出了今后质子交换膜研究的发展方向。更多还原

【Abstract】 Proton exchange membrane is one of the key components of hydrogen fuel cell. However, the performance of the membrane cannot satisfy the requirement of modern society. So, lots of researches have been carried out to improve the performance. The development of various types of proton exchange membranes were introduced,including the perfluorinated sulfonic acid proton exchange membrane, partially fluorinated proton exchange membrane, non fluorinated proton exchange membrane and composite proton exchange membrane. The modification methods of the proton exchange membrane as well as the current situation of high temperature proton exchange membrane and methanol resistance proton exchange membrane were reviewed. This study pointed out the characteristics and problems of current proton exchange membrane researches, simultaneously put forwarded the direction of the development of the proton exchange membrane in the future.更多还原
