摘要
The development of clean and efficient renewable energy is an inevitable trend in the future energy transition. Hydrogen, as a green and pollution-free energy carrier can achieve efficient conversion of hydrogen energy and electric energy via water electrolysis technology, which is expected to be an important regulating means of wind and photovoltaic power generation. Water electrolysis produces hydrogen without pollutant emission, which is expected to be used as an efficient tool to storage and regulate the intermittent power of wind and photovoltaic generation. Comparing with the conventional water electrolysis using alkaline aqueous solution, water electrolysis based-on alkaline membrane can increase current density and improve energy conversion efficiency. Moreover, non-precious metals such as iron and nickel can be used to prepare catalysts for both hydrogen emission reaction (HER) and oxygen emission reaction (OER), no suffering from the drawbacks of expensive resources caused by the use of precious metal catalysts in proton exchange membrane electrolysis of water (PEMWE). In this study, we review the present status of alkaline membrane electrolysis technology for hydrogen production, focusing on self-supported catalytic electrode, alkali corrosion resistant anion exchange membranes (AEMs) and ordered membrane electrode assembles (MEA), including the preparation strategy of self-supported catalysts, the development trend of alkali corrosion resistant ion membrane and advantages of ordered MEA, explaining the coupling principle of mass transfer and reaction in electrochemical engineering. Therefore, this paper will provide guidance for further research of high-performance electrochemical key materials, and promote the development of hydrogen production technology from water electrolysis. © 2021, Editorial Board of CIESC Journal.
