Preparation method of high-transmission-performance membrane electrode of power fuel cell

The invention relates to a preparation method of a high-transmission-performance membrane electrode of a power fuel cell, which is characterized in that a hydrophilic functional group is added into an electrode aiming at the property of anode liquid fuel through hydrophilic treatment on a gas diffusion electrode, so that the hydrophilicity of the electrode is improved. The mass transfer performance of the gas diffusion electrode is improved by oxidizing the material of the support layer, adding a hydrophilic ionic polymer Nafion into the microporous layer and using a hydrophilic material as the catalyst layer. By adopting the method disclosed by the invention, the membrane electrode with high transmission performance can be prepared, and the performance of a direct liquid fuel cell is effectively improved. 本发明涉及一种动力燃料电池高传输性能膜电极的制备方法，通过对气体扩散电极的亲水处理，针对阳极液体燃料的性质，在电极中添加亲水性官能团从而提高电极的亲水性。通过对支撑层材料的氧化、在微孔层加入亲水的离子聚合物Nafion、使用具有亲水性质的材料作催化层来改善气体扩散电极的传质性能。采用本发明的方法能够制备出具有高传输性能的膜电极，有效提升直接液体燃料电池的性能。
