PEM hydrogen generator hydrogen electricity production

Product Description:

Proton exchange membrane as a special solid electrolyte Compared with traditional liquid electrolyte, proton exchange membrane does not exist as a traditional solution, so there is no solution voltage drop, and at the same time, the proton exchange membrane has ion selective permeability, only hydrogen ions can pass through protons The exchange membrane goes to the other side, which reduces the resistance and separates the hydrogen production stage from the ion transfer stage, thus greatly improving energy efficiency.The commonly used proton exchange membrane is Nafion membrane, that is, perfluorosulfonic acid ion exchange membrane, which is a kind of polymer resin.

Factors Affecting Hydrogen Production by Electrolysis of Water:
Nowadays, the technology of hydrogen production by electrolysis of water is still immature, and various problems in the process of hydrogen production by electrolysis of water will affect the electrolysis effect. Through the analysis of the principle of hydrogen production by electrolysis of water, the influencing factors mainly include electrode materials, catalysts, electrolyte temperature, electrolyte properties, and hydrogen evolution voltage.

Working Principle:  
Electrolytic water meeting the requirements (with electrical resistivity > 1MΩ/ cm) , after being put into the anode chamber of electrolytic cell , when power is switched on ,wil l be decomposed at once at the anode : 2H2O = 4H+ + 2O-2. The decomposed negative oxyanion (O-2) will immediately release electron to form oxygen (O2) gas.The hydrogen proton , in the form of aqua ion (H+.XH2 O) , and under the action of electric field force , through SPE ion membrane, will arrive in the cathode to absorb electron to form hydrogen gas.
