摘　　要：质子交换膜燃料电池膜电极组件的性能受限于氢气与氧气在催化层中的不均匀分布。为了促进氢气与氧气在催化层中的扩散,本文使用结合了电势置换反应的新型浸渍法在质子交换膜上沉积一层具有电催化活性的Pt基合金纳米颗粒,形成了超薄的不含碳载体的催化层。在与碳纸复合后即可获得正常工作的新型膜电极。经测试,超薄催化层能提高膜电极的贵金属利用率,降低其制备成本,有利于推动质子交换膜燃料电池与相关产业的发展。The performance of proton exchange membrane fuel cell membrane electrode components is limited by the uneven distribu-tion of hydrogen and oxygen in the catalytic layer.In order to promote the diffusion of hydrogen and oxygen in the catalytic layer,a novel impregna-tion method combining potential displacement reaction was used to deposit a layer of electrocatalytic Pt based alloy nanoparticles on the proton ex-change membrane,forming an ultra-thin catalytic layer without carbon carriers.After being combined with carbon paper,a new type of membrane electrode can be obtained that works normally.After testing,the ultra-thin catalytic layer can improve the utilization rate of precious metals in mem-brane electrodes,reduce their preparation costs,and promote the development of proton exchange membrane fuel cells and related industries.
