摘　　要：膜电极(MEA)是质子交换膜(PEM)电解堆的核心,是物质传输和电化学反应的场所,直接决定电解堆的性能、成本和寿命。综述了PEM电解制氢膜电极的制备方法,主要包括:多孔传输层表面制备催化层(PTE)、质子交换膜表面制备催化层(CCM)、有序化制备法(OME)及直接膜沉积法(DMD)。PTE工艺可避免质子膜溶胀,但对传输层孔隙结构要求较高;CCM工艺过程简单,具有良好的催化层/膜界面,但电极极化损失高、物质传输性能较低;OME工艺具有良好的导电性及物质传输通道,有助于增加三相界面;DMD工艺可改善催化层与质子膜界面,自由调节膜厚,提升膜电极的性能并降低成本。The MEA is the core of the PEM electrolysis stack,which is the site for material transport and electrochemical reactions,determining the performance,cost and lifespan of the electrolysis stack.The preparation methods of PEM electrolysis membrane electrodes were reviewed,mainly including porous transport layer surface preparation catalytic layer(PTE),membrane surface preparation catalytic layer(CCM),ordered preparation method(OME),and direct membrane deposition method(DMD).The PTE could avoid membrane swelling,but it had high requirements for the pore structure of the transport layer.The CCM was simple and good catalytic/membrane interface,but the electrode polarization loss was high and the material transfer performance was low.The OME had good conductivity and transfer channels,which helped to increase the three-phase interface.The DMD improve the interface between the catalytic layer and the membrane,freely adjust the membrane thickness,enhance the performance of the membrane electrode,and reduce costs.
