The electrolytic cell consists of a tank body, an anode and a cathode. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution. Pure water is used as raw material to produce hydrogen and oxygen, which is green and environmentally friendly. Very widespread in industrial applications, it can provide clean energy for automotive, home and industrial applications, providing higher efficiency than fuel cells. It adopts high current density design, which has the advantages of high purity of oxygen production, low energy consumption for hydrogen production, high system efficiency, and high system adaptability.
