The working principle of the hydrogen generator. The hydrogen produced by the hydrogen generator comes from two different sources.
1. The qualified electrolytic water (with a resistivity greater than 1M Ω/cm, deionized water or secondary distilled water for electronic or analytical industries can be used) is sent to the anode chamber of the electrolytic cell for hydrogen production by pure water electrolysis. After power on, the water is immediately decomposed at the anode: 2H2O=4H++2O-2, the negative oxygen ions (O-2) decomposed into, then electrons are released at the anode to form oxygen (O2), which is discharged from the anode chamber, and part of the water is carried into the tank. The water can be recycled, Oxygen is discharged into the atmosphere from the small hole on the tank cover. Hydrogen protons, in the form of hydrated ions (H+XH2O), under the action of electric field force, pass through the SPE ion membrane, reach the cathode to absorb electrons and form hydrogen. After being discharged from the cathode chamber, they enter the gas water separator where most of the water carried from the electrolytic cell is removed. The purity of hydrogen containing trace water will reach above 99.999% after being absorbed by the dryer.
2. The working principle of hydrogen production by alkaline solution electrolysis is the traditional diaphragm alkaline solution electrolysis method. The conductive medium in the electrolytic cell is potassium hydroxide aqueous solution. The separator of the bipolar chamber is a high-quality diaphragm for aerospace electrolysis equipment. The electrolytic cell is composed of a grid electrode with corrosion resistance and good mass transfer integrated with the end plate. After applying direct current to the two poles, the water molecules will immediately undergo electrochemical reactions at the two poles of the electrolytic cell, generating oxygen at the anode and hydrogen at the cathode. The reaction formula is as follows: anode: 2OH -- 2e → H2O+1/2O2 ↑ cathode: 2H2O+2e → 2OH -+H2 ↑ total reaction formula: 2H2O → 2 H2 ↑+O2 ↑ This instrument implements automatic control for voltage control, overvoltage protection, flow display, flow tracking, etc; The output hydrogen can be adjusted automatically (within the range of gas production) under constant pressure according to the amount of hydrogen used by the gas chromatograph.
