The working principle of a hydrogen generator The working principle of a hydrogen generator is based on the electrolysis of water technology. It generates hydrogen by decomposing water molecules through an electric current. It mainly consists of four core steps: electrolysis, separation, purificatio
Electrolysis stage: Current passes through the electrolytic cell, and water molecules undergo oxidation-reduction reactions at the electrodes. Hydrogen gas is produced at the cathode, and oxygen gas is produced at the anode. In pure water type equipment, the gases are isolated by a PEM membrane to prevent mixing, while in alkaline type equipment, ion conduction is achieved through a liquid electrolyte.
Pure water type (PEM electrolysis): Only pure water is electrolyzed, no alkaline substances are added. A titanium alloy electrolytic cell and a stainless steel gas path structure are adopted. The advantages include high hydrogen purity (≥99.999%), low power consumption (about 150W), zero pollution, but the costs of PEM membranes and catalysts are relatively high.
