Description

Technical Field

[0001] The utility model relates to the field of chemical engineering, in particular to a water electrolysis hydrogen production device. Background Art

[0002] Water electrolysis is a mature and environmentally friendly method for hydrogen production and has been widely used in the industrial and energy sectors. Conventional water electrolysis hydrogen production devices mostly use alkaline or proton exchange membrane (PEM) technology. Direct current is passed through an electrolyzer filled with an electrolyte solution (such as potassium hydroxide or sodium hydroxide solution), decomposing water into hydrogen and oxygen. However, existing water electrolysis devices have several limitations, particularly in terms of system maintenance and operational flexibility.

[0003] Most water electrolysis equipment currently on the market uses a single or small number of large electrolytic cell structures. Although this design can achieve large-scale continuous production, once the components inside the electrolytic cell, such as the exchange membrane or electrodes, fail or age, the entire system often needs to be stopped for repair or replacement. This not only leads to production interruptions, but also greatly increases maintenance costs and time. Utility Model Content
