直接甲醇燃料电池高阻醇质子交换膜的研究进展

Research progress of high methanol-preventing proton exchange membranes for direct methanol fuel cells

为降低甲醇的渗透,提高直接甲醇燃料电池的性能,许多研究者致力于低甲醇渗透质子交换膜的研究。每种膜都有优缺点,综述了改性Nafion膜及其替代膜的研究现状,指出它们在直接甲醇燃料电池中的应用前景。

In order to reduce methanol crossover, and improve the performance of direct methanol fuel cells, many researchers are applying themselves to the research of the proton exchange membranes with low methanol permeability. Each membrane has its advantages and disadvantages. The research progress of the modified Nafion membranes and their substitutes were reviewed, their prospect for direct methanol fuel ceils were also pointed out.
