Electrolysis System

The main component of the electrolysis system is an electrolyzer stack, where water in the electrolyzer is electrolyzed into hydrogen and oxygen under the action of direct current.

Total Reaction Formula: 2H2O = 2H2↑ + O2↑

Cathode Reaction Formula on Cathode: 4H2O + 4e- = 2H2↑ + 4OH-

Reaction Formula on Anode: 4OH- = O2↑ + 2H2O + 4e-

Each electrolytic cell of the electrolyzer stack is further divided into an anode cell and a cathode cell. The electrolyzer stack is filled with 30% KOH aqueous solution (referred to as electrolyte), where hydrogen is produced in the cathode cell and oxygen is produced in the anode cell. The hydrogen gas and electrolyte undergo gas-liquid separation in a separator, and the hydrogen gas is then cooled, dehydrated, pressurized, and delivered to the next process.
