As global demands for clean energy and sustainable development continue to grow

alkaline water electrolysis has emerged as a key technology for the production of green hydrogen

becoming a core technology in the domestic hydrogen energy industry. This study aims to screen and optimize commonly used electrode and membrane materials in the market

clarifies the current performance status of commercial electrode and membrane materials

and further investigates the impact of various components on electrolysis energy consumption. The results show that electrode materials doped with transition metal elements can significantly enhance electrolysis efficiency

demonstrating excellent electrocatalytic performance. Single cells with cathode materials doped with Mo elements can achieve a current density of 425 mA/cm2 at 1.8 V@80 ℃. Additionally

composite membrane materials with low surface resistance and high wettability exhibit outstanding overall cell performance. For electrode materials containing transition metal elements

the mass transfer overpotential gradually becomes the main limiting factor as current density increases. This study provides a design basis for the development of the next generation of high-efficiency alkaline water electrolyzers

contributing to further improvements in electrolysis efficiency and reductions in energy consumption

thereby promoting the continuous advancement of alkaline water electrolysis hydrogen production technology.
