SHC series Hydrogen Generators are the electrolysis of KOH liquid to produce hydrogen. This generator meets the requirements of many types of gas chromatographs at home and abroad. The operational principle of this instrument is traditional electrolyzing lye. The conducting medium in the cell is the water solution of KOH. The membrane between the two electrode chambers is for the navigation electrolysis equipment. After electrifying direct current, the electrochemical reaction of the water molecule occurs. It produces oxygen at the anode and hydrogen at the cathode. The reaction equation is as follows:

Anode: 2OH--2e → H2 (1/2)O2
Cathode: 2H2O 2e → 2OH- H2
Final Reaction Equation: 2H2O → 2 H2 ↑ O2

The pressure control, protective pressure, flow display, and flow tracking are all automatically controlled. The hydrogen output is self-regulated according to the use of the hydrogen flow under stable pressure (in the range of output flow).
