中文摘要：

将不同规格的微孔膜覆盖于锌空气电池气体扩散电极表面，探究微孔膜对锌空气电池失水和性能的影响。实验结果表明：在微孔间距小于临界间距时，覆盖微孔膜可使锌空气电池的失水量减少40％～80％，而不会阻碍氧气的传输。微孔数目越少，电池失水量越少，放电性能也越好。当微孔间距达到临界值时，电池失水量达到最小值。氧气在微孔膜上的通量远高于水蒸汽在微孔膜上的通量。

英文摘要：

In order to explore the influence of microporous membrane on the dehydration and performance of zinc-air battery, microporous membrane with different specifications was covered on the gas diffusion electrode surface of a zinc-air battery. Experimental results indicate that when microporous spacing is less than the critical spacing, the membrane can reduce dehydration of zinc-air battery from 40% to 80%, while will not hinder the transmission of oxygen. The less the number of micropores is, the water loss of battery is less, the battery discharge performance is better. When microporous spacing reaches the critical value, the dehydration of battery reaches the minimum value. The oxygen flux through microporous membrane is much higher than that of water vapor.
