Water electrolysis is a relatively convenient method for producing hydrogen gas.
In an electrolytic cell filled with electrolyte, direct current is applied, and water molecules undergo electrochemical reactions on the electrode, decomposing into hydrogen and oxygen.
The electrolytic cell is the core equipment for water electrolysis hydrogen production. When the electrolytic cell is connected to a DC power supply and the electrolysis current rises to a certain value, the water in the electrolytic cell is electrolyzed into hydrogen and oxygen. H2 is mainly produced in the cathode chamber, while O2 is produced in the anode chamber.
What we mainly produce are Alkaline-type hydrogen systems and PEM-type hydrogen systems.
