摘要：

Nowadays,as the energy scarce increasing,hydrogen energy has emerged as a renewable and environmental-friendly new energy source. It serves as an important energy carrier for global energy conservation and carbon reduction. Traditional alkaline water electrolysis (AWE)is the most common method for hydrogen production,but it requires alkaline solution with high pH as the electrolyte and can only operate at low current density;proton exchange membrane water electrolysis (PEMWE)technology,on the other hand,can be operated at high current density with high efficiency,making it the most promising water electrolysis technology for hydrogen production. However,the expensive catalyst and need for acid-resistant components are important challenges that hinder its development. Anion exchange membrane water electrolysis (AEMWE)is a promising new technology for green and cost-effective hydrogen production. Comparing with AWE,it avoids the circulation of concentrated alkaline solution. Comparing with PEMWE,it offers advantages such as lower cost and lower corrosiveness. Ionomers,as a key component of the triple phase boundary (TPB)in the membrane electrode assembly (MEA),play a crucial role in the catalytic capabilities and water management of AEMWE. This review firstly aims to provide an overview of AEMWE technology and the importance of ionomer in MEA. It also summarizes the structures and characteristics of representative ionomers adopted in AEMWE. Finally,this review explores strategies to improve the electrolytic performance of AEMWE through ionomer regulations from three aspects:structural regulation,content regulation and additive regulation. © 2024 Cailiao Daobaoshe/ Materials Review.
