The industry in hydrogen has developed from how to effectively gain the hydrogen gas, how to operate the machines including vehicles, trains, house and other small appliances using it, how to add value on the hydrogen gas for food or medicine, how to safely store hydrogen gas, and how to deliver these all factors work around in the economic system.
Hydrogen Byproduct Method and natural gas reformation is relatively cheap. These methods are being used in the industrial field, so it is not appropriate for inhalation in quality and environmental aspects.
Water electrolysis technology includes alkali electrolyte method and polyelectrolyte (a.k.a. Proton Exchange Membrane (PEM)) method. With this said, polyelectrolyte method is the safest way to produce hydrogen gas frequently inhaled at hospitals and homes. With this method, the water is separated into Hydrogen and Oxygen gas via PEM that uses pure white gold, titanium, so the downside is that it is expensive. Still, it allows us to inhale hydrogen with a purity of 99.9995% and was acknowledged as a technology with vast potential. On the other hand, the Alkali Electrolyte Method is a relatively old method. With this method, NaOH, an electrolysis catalyst, or calcium hydroxide, is added to the water. Even if there’s a filter to filter out the odor and contaminants, this method is not quite suitable to be used for inhalation purpose.
For the physical explosion to occur, hydrogen must be stored in a storing tank and has to be expanded with high pressure and there must be a crack on the storing tank. Hue Light’s hydrogen inhalation device emits the gas as soon as it is generated, so it does not store the hydrogen inside the device. So, there’s no storing tank inside the device.
Theoretically, chemical explosion occurs as a combustion reactivity when all of the following criteria are met: leak > gas cloud > ignition source. It is very difficult for the hydrogen to form a gas cloud because it easily diluted to the air, so it would be difficult for all aforementioned criteria to be met. However, the user should always be cautious not to ignite a cigarette, lighter and other fire igniting source in front of the opening where the hydrogen gas comes out.
Hue Light PEM Cell (1.5L~3.0L)
Polyelectrolyte System uses the proton exchange membrane (PEM) to separate the distilled water. This allows the water and cation exchange and as the membrane acts as the cell’s electrolyte, so there’s no need for chemical electrolyte such as sodium hydroxide and/or potassium.
When current voltage gets permitted, the water is provided to positive electrode and/or oxygen electrode, so it becomes oxygen, proton and free electrons. Proton (H+ ion) passes through the PEM and moves to the hydrogen electrode and meets with the electrons to convert to hydrogen gas.
The reaction process is shown as follows.
