阴离子交换膜电解水的阳极多孔传输层结构优化研究进展
Recent Advances in the Structural Optimization of the Anodic Porous Transport Layer for Anion Exchange Membrane Water Electrolysis
摘要
Abstract
Anion exchange membrane water electrolysis(AEMWE)combines the low-cost advantage of alkaline water electrolysis with the high efficiency and compactness of proton exchange membrane water electrolysis(PEMWE),making it a current research hotspot in the field of green hydrogen.However,the oxygen evolution reaction(OER)on the anode side has problems such as slow kinetics,structural instability at high potentials,and low multi-phase transport efficiency,which have become the key bottlenecks restricting the performance improvement and long-term stable operation of AEMWE.This paper focuses on the optimization design and structure-performance relation-ship of the anode porous transport layer(PTL)in AEMWE,and systematically reviews the research progress in this field in recent years.Firstly,from the regulation of structural parameters(porosity,pore size gradient,thickness)and surface property modification(hydrophilic/hydrophobic treatment,surface morphology construction)of the anode PTL,the influence mechanism of PTL on electron conduction,material transport and bubble behavior are analyzed.Secondly,the construction strategies of integrated anode electrodes are discussed in detail,including the structure of catalyst-coated porous transport layer(CCPTL),in-situ grown self-supporting electrodes,and membrane-electrode integrated design,and their advantages and challenges in enhancing interfacial activity,reducing contact resistance and improving stability are summarized.On this basis,the intrinsic correlation between the anode microstructure(pore structure,array morphology,interface bonding state)and macroscopic performance(activity,mass transfer,stability)is summarized.Fi-nally,it is proposed that future research should focus on key directions such as the dynamic evolution of the three-phase interface under multi-field coupling,the failure mechanism of integrated electrodes under fluctuating conditions,and the quantitative analysis of structure-performance relationships,to provide theoretical guidance for the rational de-sign of AEMWE anodes and the development of high-performance membrane electrodes.关键词
