The principle of hydrogen production by electrolysis of water is simple
Green hydrogen is mainly produced by electrolyzing water. The process of producing hydrogen by electrolyzing water is mainly divided into three major steps: preparation, purification, and storage. Hydrogen production: The electrolytic cell is connected to the DC power supply. When the electrolysis current rises to a certain value, the water in the cell is electrolyzed into hydrogen and oxygen. Hydrogen purification: The hydrogen electrolyzed from the cathode of the electrolysis chamber in the cell, together with the circulating alkali solution, flows through the hydrogen channel ring through the outlet hole on the cathode side of the plate with the help of the lift of the alkali solution circulation pump and the left and right end plates. flow out, merge and enter the hydrogen separator. In the hydrogen separator, hydrogen gas and alkali liquid are separated due to the effect of gravity. Hydrogen storage: The separated hydrogen is cooled by the hydrogen cooler. After the hydrogen drop catcher and hydrogen water separator remove the entrained moisture, it enters the hydrogen dryer through the differential pressure regulating valve. The dried hydrogen enters the hydrogen storage tank. Some of the hydrogen will be compressed again and liquefied into liquid hydrogen for easy transportation and storage.
