Technology
Hydrogen-assisted combustion, produced on demand
The HYMIX™ system uses distilled water to produce hydrogen and oxygen on board. The gas is used immediately — nothing is stored — and mixes with intake air for more complete combustion.
- 1
Power supply
The unit draws low-voltage power from the vehicle's electrical system.
- 2
Hydrogen generation
A submerged P.E.M. stack produces hydrogen and oxygen from distilled water and sends it straight to the air intake.
- 3
Mixing
Hydrogen and oxygen mix with incoming air in the intake before entering the engine.
- 4
Complete combustion
More complete combustion in the engine reduces smoke and harmful exhaust pollutants.
Patented submerged P.E.M. stack
- Uses distilled water (H₂O) as the only feedstock
- High-purity hydrogen and oxygen without separate purification
- Produce-and-use-immediately design — no gas storage tank
- Submerged stack design removes explosion risk from gas build-up
- Applicable to all internal combustion engines
Core patents
- Hydrogen and oxygen supply device

Core Technology
Submerged P.E.M. stack
At the heart of every HYMIX™ system is a patented submerged polymer electrolyte membrane (P.E.M.) stack. Hydrogen and oxygen are produced separately at the membrane electrodes from distilled water — with no separate purification or compression equipment.
- World's first submerged P.E.M. stack design
- Gas generated inside the water tank — removes explosion risk
- Flexible stack sizing by model (M / V / G)
- Applicable to all internal combustion engines
