Hydrogen Oxygen Separation Module for Hydrogen Water Bottle

Hydrogen and oxygen are kept apart inside the cell. An ion membrane or MEA lets hydrogen through and routes the oxygen out through its own exhaust port, so what reaches your drinking water is hydrogen, not a mixed gas - no mixed bubbles in the cup, no salt, no chemicals. Two output levels are available: 2,000 PPB with the ion membrane configuration, or 4,500 PPB with the MEA. The platinum-coated titanium electrode plates run at 0.8-1.0 A and 2.5-3.5 V, with electrode life verified to 30 hours or more in an accelerated test. The module is 43 mm in diameter, weighs 33 g, and gives you three ports: two for water and electrodes, one dedicated to the oxygen exhaust.

It is built for hydrogen-rich water bottles and vacuum cups, countertop and bench-top hydrogen water machines, portable H2 generators, wellness and beauty appliances such as face misters and antioxidant water devices, water-ionizer platforms, and OEM appliance integration inside any defined envelope.

We are the factory, not a trading company. HOMIXE runs its own electrode coating line, its own R&D team and its own mould shop in Foshan - so a custom housing, a new port layout or a different membrane configuration is developed and tooled in-house rather than outsourced. Every batch is life-tested and leak-tested before packing, and orders are traceable from a 1-10 piece sample through to OEM production.

How the Separation Module Works

It is a small water electrolyser running on low-voltage DC. Water sits against two platinum-coated titanium electrode plates. Apply current and the electrical energy splits the water molecules: hydrogen forms at the negative electrode as H₂, oxygen forms at the positive electrode as O₂. Nothing is added to the water — no salt, no electrolyte, no chemicals.


What makes this module different from a non-separation type is the membrane sitting between the electrodes. It is permeable to hydrogen but blocks oxygen, and the oxygen is routed to its own exhaust nozzle. Hydrogen is carried into the drinking water; oxygen leaves the bottle. The two gases never recombine inside the cup, which is why the separation type reaches a higher hydrogen concentration and gives a cleaner drinking experience.

What you get with separation

• Higher hydrogen concentration — up to ≥ 4,500 PPB with the MEA configuration

• Oxygen leaves through a dedicated exhaust port instead of entering the water

•No mixed-gas bubbles in the cup

• Supports a PPB claim on your retail packaging

• Preferred architecture for premium bottles and countertop machines

What it asks of your design

•One extra tube and nozzle position for the oxygen exhaust

•Slightly larger envelope than non-separation — Ø43 mm, 33 g

• A constant-current drive between 0.8 and 1.0 A

• Water kept between ambient and 60 °C, module stored damp

•Membrane activation (soak) before first use

Installation & Handling Notes

Six points that decide whether the module performs to spec in the field.

  • Activate the membrane first. Soak the module in cold water for 10 hours, or in 50–60 °C warm water for 1 hour. This activates the membrane and you get a noticeably stronger bubble output from the first cycle.
  • Polarity matters. Wire the module backwards and output collapses — you will see a very small gas volume with oxygen appearing on the hydrogen side. Polarity is marked on the module body.

  • Keep it wet. Store the module damp when it is not in use. A membrane left to dry out is damaged and its performance drops permanently.

  • Water temperature ≤ 60 °C. Above 60 °C the module is damaged, and any hydrogen produced escapes from the water very quickly.

  • Fastening. M2.5 screws. Specify titanium screws for better corrosion resistance — length to your drawing.

  • Leak check before you commit. Close the bottle cap, run 30 minutes of continuous electrolysis, then rest 30 minutes. No leakage is acceptable.


Quality Assurance — Every Module Tested Before It Ships

This module goes inside somebody's drinking-water product. Each batch is tested in-house, not sampled at random.

Documents issued with your order on request

2. Working current test — constant current 1 A, voltage confirmed below 3.5 V

3. Working temperature test — RO water, 10 minutes of electrolysis, water temperature must stay below 45 °C

4. Pressure / leak test — 30 minutes continuous electrolysis with the cap on, then 30 minutes at rest, no leakage permitted

5. Appearance & dimensional check — electrode spacing, terminals and housing inspected before packing

Is the Separation Module Always the Right Answer?

No — and we make both, so we will tell you honestly. If your bottle is slim, your volume is high and unit cost is the deciding factor, the hydrogen-oxygen non-separation module (HM-HONS8428) gets you a working product for less: no membrane, no exhaust tube, only 12 g and 12.5 mm thick. The trade-off is a lower achievable hydrogen concentration and a mixed gas entering the water.
