Core Technology and Operational Principles

At the heart of the QL-300 Hydrogen Gas Generator lies its advanced SPE technology. This technology enables the efficient electrolysis of pure water to produce high-purity hydrogen gas without the need for alkaline solutions. Here's a closer look at how the generator works:

1. Electrolysis of Pure Water
   High-purity water, meeting the resistivity requirement, is introduced into the anode chamber of the electrolysis cell. Upon applying electrical current, the water molecules undergo electrolysis, splitting into hydrogen ions (H+) and oxygen ions (O2-).

2. Formation of Oxygen
   The oxygen ions released at the anode combine with electrons to form oxygen gas (O2), which is then vented out of the system. Part of the water carrying the oxygen ions enters the water tank for recycling.

3. Migration of Hydrogen Ions
   The hydrogen ions, in the form of hydrated ions (H+•XH2O), migrate through the SPE membrane under the influence of an electric field. These ions reach the cathode, where they combine with electrons to form hydrogen gas (H2).

4. Gas-Water Separation and Drying
   The hydrogen gas exiting the cathode chamber passes through a gas-water separator to remove excess moisture. The slightly damp hydrogen is then further dried using a desiccant to achieve the desired purity level of over 99.999%.
