利用化学镀的方法制备了不同厚度的钯膜，着重研究了乙醇水蒸气重整反应气氛下钯膜的透氢性能. 实验结果表明573-623K时，乙醇氢气混合气(Et/H2)气氛对钯膜透氢性能的影响大于乙醇水蒸气混合气(Et/H2O)气氛；623-673K时，Et/H2O气氛对钯膜透氢性能的影响大于Et/H2气氛.当钯膜暴露在H2/N2/Et和H2/N2/Et/H2O气氛下50min后，透氢量分别能恢复至初始值的96%和89%.此外，乙醇水蒸气重整反应气氛中，较大的水醇比（10-13）和较薄的钯膜（2-6µm）有利于抑制钯膜透氢量的下降.

 In this paper, different thicknesses of palladium membrane were prepared by chemical plating and the effect of ethanol on hydrogen permeation of palladium membrane was foced on investigating. The results showed that the influence of Et/H2 atmosphere on hydrogen permeation of palladium membrane was more serious than  Et/H2O atmosphere at low temperature (573-623K). While it is completely opposite at high temperature (623-673K). Moreover, exposure tests of different atmospheres showed that hydrogen permeation value restored to 96% and 89% of the initial value in H2/N2/Et and H2/N2/Et/H2O atmosphere, respectively. In addition, larger water ethanol ratio (10-13) and thinner palladium membrane (2-6 µm) were in favor of suppressing the effect of ethanol on the hydrogen permeation of palladium membrane.
