摘要
Abstract
For investigating the laws of gas permeation in proton exchange membrane fuel cells,the effects of temperature,humidity and membrane thickness on the permeability of H2,O2 and N2 were investigated by a combination of theoretical calculations and experimental verification.The results showed that the gas permeability of different thicknesses of membranes increased with the increase of relative humidity and temperature,and the ratio of the permeability of H2,O2 and N2 gases in the two types of membranes,MX20 and M740,was about 5∶2∶1.In addition,the increase of membrane thickness also significantly reduced the permeability of gases.The permeability of three gases,H2,O2 and N2,decreased by 20.6%,22.1%and 21.8%,respectively,when the thickness of the membrane was increased from 10μm to 18μm.These studies contributed to a clearer understanding of the mechanism of gas permeation in proton exchange membrane fuel cells and provided a reference basis for optimizing the design of membrane materials.关键词
