1) Customizable pem electrolyzer China uses a proton exchange membrane to isolate the gas on both sides of the electrode, avoiding the disadvantage of easy gas permeation of the alkaline electrolytic hydrogen production diaphragm. (2) The equipment mainly includes Customizable pem electrolyzer China and BOP; (3) The current cost is relatively high.

Hydrogen production by electrolysis of water in pem electrolytic cell means that the DC power supply enters the electrolytic cell filled with electrolyte solution, and the water produces electrochemical reaction on the metal electrode, which can be decomposed into hydrogen and oxygen, and the whole process can complete zero emission. In the overall production chain, the pem electrolyzer is the main medium of the facility.

The distance between the cathode and anode of alkaline electrolyzers in China is one of the important factors affecting the cell voltage. As the electrode spacing increases, the ohmic voltage drop in the slot increases, and the slot voltage increases.

The main structure of pem electrolyzer is similar to fuel cell stack, which is divided into membrane electrode, electrode plate and gas diffusion layer. The anode of the PEM electrolytic cell is in a strongly acidic environment (pH≈2) and the electrolysis voltage is 1.4~2.0 V. Most non-precious metals will corrode and may combine with the sulfonate ions in the PEM electrolytic cell, thereby reducing the ability of the PEM to conduct protons.
