The Origin Of Hydrogen Generator And Its Comparison



How does a hydrogen generator produce hydrogen, it has two main sources.

Here is a simple comparison of the two principles:

Electrolytic hydrogen production

The working principle is that the traditional diaphragm electrolysis method. The conductive medium in the electrolytic tank for potassium hydroxide aqueous solution, separation of the two chambers for aerospace electrolysis equipment with high-quality diaphragm, and end plate corrosion and integrated mass transfer good grid electrode composed of electrolytic cell. When the DC is applied to the poles, the water molecules react immediately at the poles of the cell. The oxygen is produced in the anode and hydrogen is produced at the cathode. The reaction equation as follows: 2OH--2e: H2O+1/2O2 = - anode cathode: 2H2O +2e 2OH- +H2, the total reaction type: 2H2O, H2 = 2 = +O2 = the instrument of pressure control, overvoltage protection, flow display, flow tracing are the implementation of automatic control; the output of hydrogen at constant pressure, according to gas chromatography with hydrogen gas the spectrometer, automatic regulation (in gas range).

Two, pure water electrolysis hydrogen production

To meet the requirements of water electrolysis (resistivity greater than 1M /cm, deionized water or electronic analysis for the industry or two times in distilled water can be) into the anode chamber of the electrolytic bath, the water immediately after power on the anode decomposition: 2H2O=4H++ 2O-2, negative oxygen ion decomposition into (O-2), then release electrons at the anode. The formation of oxygen (O2), discharged from the anode chamber, carrying some water into the water tank, the water can be recycled, oxygen from the tank cover holes into the atmosphere. Hydrogen proton to hydrated ions (H+? XH2O) in the form of action of electric field force, through the SPE membrane, reach the cathode absorption electrons to form hydrogen, discharged from the cathode chamber, into the gas water separator, then remove most of the water carrying out from the electrolyzer, hydrogen gas containing trace water by the dryer after moisture absorption. The purity was more than 99.999%.
