主　　题：hydrogen production anion exchange membrane water electrolyzer catalyst membrane electrode assembly 

摘      要：Anion exchange membrane(AEM)electrolysis is a promising membrane-based green hydrogen production ***,AEM electrolysis still remains in its infancy,and the performance of AEM electrolyzers is far behind that of well-developed alkaline and proton exchange membrane ***,breaking through the technical barriers of AEM electrolyzers is *** the basis of the analysis of the electrochemical performance tested in a single cell,electrochemical impedance spectroscopy,and the number of active sites,we evaluated the main technical factors that affect AEM *** factors included catalyst layer manufacturing(e.g.,catalyst,carbon black,and anionic ionomer)loadings,membrane electrode assembly,and testing conditions(e.g.,the KOH concentration in the electrolyte,electrolyte feeding mode,and operating temperature).The underlying mechanisms of the effects of these factors on AEM electrolyzer performance were also *** irreversible voltage loss in the AEM electrolyzer was concluded to be mainly associated with the kinetics of the electrode reaction and the transport of electrons,ions,and gas-phase products involved in *** on the study results,the performance and stability of AEM electrolyzers were significantly improved.
