The purity of the molecular hydrogen generated by the electrolytic cell depends on the quality of the cell's construction. It can be said without a doubt that the quality of an H2 inhalation device depends entirely on the quality of the SPE cell's construction materials and the stability of its power supply (voltage). The HYDROXION electrolytic cell is manufactured directly by the supplier and operates at a supply voltage of 1.8 V, while other SPE cell manufacturers set the supply voltage to a higher value of 2.0-2.2 V. As the SPE cell ages over time, its base voltage "drifts" toward higher values until it reaches the critical value of 3.5 V, at which the cell's H2 synthesis efficiency is minimal. When the supply voltage exceeds 3.5 V, the H2 mixture could become enriched with ozone, a gaseous species harmful to the respiratory tract. For these important reasons, the manufacturer uses iridium as the insulation material for the SPE cells; iridium is very expensive, but it ensures greater stability of the power source (the voltage of 1.8 V remains more stable over time and is less likely to drift to higher values) and operating temperature. These cell insulation characteristics are closely related to the efficiency and stability of molecular H2 synthesis over the long term. The supply current for each electrolysis plate was set to 20-25 A, corresponding to the production of a volume of H2 per plate equal to 150-200 ml.
Therefore, there is a direct proportionality between the value of the supply current and the volume of H2 synthesis per plate. Increasing the value of the current would theoretically increase the volume of H2 generated (except if this would adversely affect operational reliability and increase wear).
In order not to sacrifice the aspects of operational stability and longevity of the electrolytic cell, the manufacturer has decided not to power the electrolytic plates with a current value exceeding 20-25 A.
The proton exchange membrane is of the DUPONT 117 type, characterised by extreme construction quality and a thickness of 180 micrometres.
The device's power cord is medical-grade to ensure stable power. The quality construction of the device's internal circuitry and its aluminum outer shell ensure low operating noise, good heat dissipation, and added value in terms of aesthetic appeal and the longevity of the entire construction.
The device is CE, FCC, UL, PSE, and RoHS certified and has been tested and approved by professional laboratories and institutes for the use of molecular hydrogen in the United States. Finally, the manufacturer provides a three-year warranty, although HYDROXION has proven to be still perfectly efficient after five years of commercial use.
