The Highdrogen® Age2 Go generates hydrogen gas to dissolve it in drinking water. Hydrogen gas is recovered from the filled water by a special electrolysis cell. This so-called PEM cell corresponds to the inversion of a fuel cell. The difference is, the energy of the molecular gaseous hydrogen is not burned by oxygen to generate electricity, but the electricity is used to extract hydrogen and oxygen from water. The used electrical energy is stored almost exclusively in hydrogen. The oxygen is to be understood as waste, which is not dissolved in the water, but released through a small hole in the housing into the air. A characteristic of drinking water in which molecular hydrogen is dissolved is that it has a negative electrical voltage shown by a measuring electrode, the so-called negative redox potential. The lower the redox potential, the higher the readiness of the water to release electrons. This readiness is doubled per 0.018 volt (18 millivolts) lower redox potential. The Highdrogen® Age2 Go generates around a 400 to 800 millivolts lower redox potential than tap water or bottled water.
