氢能是我国2060年“碳中和”的关键支撑,氢气制备又是氢能产业链“制、储、输、用”四大环节中的首要环节,绿色高效地制取氢气是氢能发展的基础。阴离子交换膜电解水(AEMWE)作为新兴的“绿氢”技术,充分结合了碱性水电解技术与质子交换膜电解技术的优势,有望成为最具发展潜力的可再生能源制氢技术。对AEMWE的原理与研究现状做了简要分析,详细论述阴离子交换膜(AEM)水电解槽关键部件的研究进展与发展方向,包括阴离子交换膜、阳极、阴极催化剂、双功能催化剂、离聚物、膜电极、多孔传输层、双极板及电解液。最后结合研究现状,展望了AEMWE制氢技术的研究方向。

Hydrogen energy is the key support for China's"carbon neutrality"in 2060,and hydrogen preparation is the primary link in the four major links of the hydrogen energy industry chain,namely"production,storage,transmission,and use".The green and efficient production of hydrogen is the basis for the development of hydrogen energy.Anion exchange membrane water electrolysis(AEMWE),as an emerging"green hydrogen"technology,fully combines the advantages of alkaline water electrolysis and proton exchange membrane electrolysis technology,and is expected to become the most promising renewable energy hydrogen production technology.This paper briefly analyzes the principle and research status of AEMWE,and discusses in detail the research progress and development direction of key component of anion exchange membrane(AEM)water electrolyzer,including anion-exchange membrane,anode,cathode catalyst,bifunctional catalyst,ionomer,membrane electrodes,porous transport layer,bipolar plate,and electrolyte.Finally,in light of the current research status,the research and development direction of hydrogen production technology by AEMWE is envisioned.
