The unique technology of KENCOS

Learn how KENCOS works and how it produces hydrogen gas.


So how does KENCOS actually produce hydrogen?



KENCOS produces molecular hydrogen via the process of electrolysis.

Electrolysis is the process of using electricity to split water into hydrogen and oxygen. This process takes place within an electrolyzer.

Inside KENCOS’s tank are electrodes made of platinum and titanium. These carry the electric current and deliver them to the specially formulated electrolysis liquid solution. This solution contains sodium citrate and pure water. The sodium citrate is there simply to act as a conductor, which pulls in the electrical current, which in turn splits pure water into 66.6% hydrogen and 33.3% oxygen. As you breathe through the mouthpiece of the unit, you are directly breathing this gas into your lungs.

Electrolysis is the most practical way to produce hydrogen in inhalers as it avoids the need to store excess gasses and simply allows the user to inhale the hydrogen as it is produced.

A common question we receive is “Why can I simply not use tap water to generate the hydrogen instead of a specially formulated solution?”

The answer to this is actually tap water will certainly work in achieving electrolysis, however the danger with this is the tap water is not purified and will be contaminated, adding harmful contaminations to the gas that you inhale.

Pure water will not conduct electricity, so the electrolysis solution that KENCOS uses is pure water with just a small amount of sodium citrate to conduct the electric current.

What are the benefits of electrolysis?

In hydrogen inhalation devices electrolysis is preferred as this will generate pure hydrogen without emitting any harmful gases into the atmosphere, meaning KENCOS can produce hydrogen simply and effectively without any greenhouse gas emissions.

The science of electrolysis as well whilst very specific, is simple to understand and execute. This technology is utilized by KENCOS effectively to deliver hydrogen on the go.


KENCOS specifications

Designed and made in Japan


KENCOS is designed and manufactured by AquaBank Co., Ltd. in Japan. It is designed to ensure that the user experiences a high-quality product that not only performs as it should, but also is comfortable and safe to use.

Does the flow rate suffer due to KENCOS’s small design?

KENCOS came from the idea of being able to supply customers with a convenient method of hydrogen inhalation whilst still maintaining the benefits that can be felt from inhaling hydrogen from the large, non-portable machines. Knowing the flow rate would be lower, AquaBank cooperated with a national university In Japan to conduct research based on KENCOS’s maximum 8ml per-minute hydrogen flow rates.

The results show that as long as used regularly, hydrogen even at this flow rate can still potentially offer the refreshment effect.
