Hydrogen is an ideal clean energy source that can be used as an energy storage medium for renewable energy sources. The water electrolysis hydrogen production technology, which is one of the mainstream hydrogen production methods, can be used to produce high-purity hydrogen and other energy sources can be converted into hydrogen storage by electrolysis. Hydrogen production by alkaline water electrolysis and hydrogen production by PEM electrolysis are all water electrolysis hydrogen production technologies that have been industrially applied. From the application point of view, the paper compares the working principle of the two kinds of electrolyzers, the process flow of hydrogen production equipment, advantages and disadvantages. This article provides a reference for relevant researchers.
