| 摘 要： | 甲醇从阳极到阴极的渗透是影响直接甲醇燃料电池性能的主要因素之一。对甲醇渗透问题进行了综述,重点介绍了阻甲醇渗透技术。近年来,阻甲醇渗透技术的研究主要集中在对全氟磺酸膜如Nafion膜的改性以及其他新型聚合物电解质膜的研制上,此外还可以通过电池操作条件的改变以及电极结构的优化来消除或减少甲醇渗透的影响。

| Abstract: | The methanol crossover from anode to cathode was one of the most important factors affecting the performance of direct methanol fuel cells. The issue of methanol crossover was reviewed and the technologies of suppression methanol crossover were especially discussed.The research of suppression methanol crossover was presently concentrated on modification of perfluoro-sulfonic membranes such as Nafion membranes and development of new polymer electrolyte membrane. Change of DMFC operation condition and electrode structure optimization were also employed to suppress or to reduce methanol crossover at least to some extent. |
