车用质子交换膜燃料电池膜电极边框研究进展

Research Progress on MEA Frame of Proton Exchange Membrane for Fuel Cell Vehicles

膜电极边框是膜电极的重要组成部分,随着燃料电池的发展,膜电极边框也越来越受到重视。对目前边框应用的材料进行了总结,将膜电极边框的结构按照使用边框的层数进行了分类,阐述了每种边框结构的封装方式。对边框测试方法进行了综述,对比了不同边框材料的物理性能,分析目前聚萘二甲酸乙二醇酯(PEN)材料成为主流的原因,并对边框不同胶层的耐久性做了试验。试验结果表明,压敏胶层的耐久性能更好。

Membrane electrode frames are important part of membrane electrodes.With the development of fuel cells,membrane electrode frames have received increasing attention.The materials used in the current frame are summarized,the structures of the membrane electrode frames are classified according to the number of layers of the frames and packaging method of each frame structure is described.The physical properties of different frame materials are compared,the reasons why Polyethylene Naphthalate Two Formic Acid Glycol ester(PEN)materials has become the mainstream are analyzed,and the durability of different adhesive layers of the frames is tested.The test results show that the pressure sensitive adhesive layer has better durability.
