Hydrogen Gas Generator Technology
Hydrogen gas generators produce high-purity hydrogen through water electrolysis, providing a safe and convenient alternative to high-pressure hydrogen cylinders.
How Hydrogen Generators Work
Water Electrolysis Principle
Electrical Energy + Water → Hydrogen + Oxygen
2H₂O → 2H₂ + O₂ (at electrodes)
Cathode (negative): 2H₂O + 2e⁻ → H₂ + 2OH⁻
Anode (positive): 2H₂O → O₂ + 4H⁺ + 4e⁻
