Product Introduction
QL series hydrogen generators are advanced patented products, which are light , highly effective , energy-saving and of environmental protection , producing extremely pure hydrogen through the electrolysis of pure water(without adding alkali).
The SPE electrodes, as the core of the product , are highly active catalytic electrode with nearly zero distance between the electrodes , which is formed by integrating composite catalyst with and ion membrane with high electrolytic efficiency. The other key parts are all produced by use of top-grade engineering plastics dies with superior quality. With perfect electric control system, designs of the generators are advanced with reliable quality, high automaticity, extremely pure generated hydrogen, huge output, the models and specifications of the generators are complete, and the generators are widely used.
Operational Principle
Electrolytic water meeting the requirements (With electrical resistivity >1MΩ/ cm, and deionized or redistilled water in electronic and analysis industries can be used for this purpose.) , after being put into the anode chamber of electrolytic cell, when power is switched on ,will be decomposed at once at the anode : 2H2 O = 4H+ +2O-2. The decomposed negative oxyanion (O2) will immediately release electron to form oxygen (O2), which will then be discharged from the anode chamber, with some water, into the water tank. The water can be used circularly, and oxygen will be discharged from the small hole of the top cover of the water tank into the atmosphere. The hydrogen proton, in the form of aqua ion (H+ XH2O), and under the action of electric field force , through SPE ion membrane, will arrive in the cathode to absorb electron to form hydrogen ,which will then be discharged from the cathode chamber into the gas/water separator, where most of water it brought with from the electrolytic cell will be removed . The hydrogen with little water will be under moisture absorption of the desiccator, with its purity thus reaching 99.999 % or above.

SHC Series Hydrogen Generator (by electrolyzing lye)
Product Type: SHC-300//500/600
Gas Flow: Different type hydrogen generator has different gas output, from 300ml/min to 600ml/min.
Applications: Supply hydrogen for lab, gas chromatography analysis, etc.
Product Introduction
SHC series hydrogen generators produce hydrogen by electrolyzing water solution of KOH. There are many kinds of automatic control settings. It's safe and convenient, and could support all kinds of chromatogram equipment from domestic or foreign manufacturers.
Operational Principle
The operational principle of this instrument is traditonal electrolyzing lye. The conducting medium in the cell is water solution of KOH. The membrane between the two electrode chambers is for the navigation electrolysis equipment. The cell is made up with the membrane and the grid electrode with good anti-corrosion and mass transfer. After electrifying direct current, the electrochemical reaction of water molecule occurs. It produces oxygen on the anode, and hydrogen on the cathode. The reaction equation is as follows:
anode: 2OH--2e → H2O 1/2O2↑
cathode: 2H2O 2e → 2OH- H2↑
final reaction equation: 2H2O → 2 H2↑ O2↑
The pressure control, protective pressure, flow display and flow tracking are all automatic control. The hydrogen output is self-regulation according to the using hydrogen flow under stable pressure.
