High Volume PEM Electrolyzer

1.Product Introduction

Hydrogen PEM electrolyser is an advanced patented product, which is light, highly effective, energy-saving and of environmental protection, producing hydrogen and oxygen through the electrolysis of pure water (without adding alkali). That's PEM technology. 

Working Principle of PEM electrolyser hydrogen cell stack

The proton exchange membrane (PEM), which only allows water and positive ions to cross between compartments. The membrane also serves as the electrolyte in the cell, eliminating the need for hazardous liquid electrolytes such as concentrated potassium hydroxide. PEM water electrolysis simply splits pure deionized water (H2O) into its constituent parts, hydrogen (H2) and oxygen (O2), on either side of this membrane. When a DC voltage is applied to the electrolyzer, water fed to the anode, or oxygen electrode, are oxidized to oxygen and protons, while electrons are released. 

The protons (H+ ions) pass through the PEM to the cathode, or hydrogen electrode, where they meet electrons from the other side of the circuit, and are reduced to hydrogen gas. The two reactions that occur in the cell are as follows:

2.2H₂O  -> 4H⁺ + 4e^- +O₂

3.4H⁺ + 4e^- -> 2H₂

4.Thus, the only possible components of the streams are hydrogen, oxygen and water moisture, as shown in Figure 1 below.

4.Product Details

Instructions: 

Connect correctly as drawing, water enters from inlet 2 and flows out from outlet 1 to ensure electrolysis

fully watered and maintained for 2-3 minutes. The other side is the same operation, from the plug 4 fill

water. When hydrogen outlet #3 flow out water, simultaneously block #4 by plug, and maintain 2-3

minutes, and then power on, to start electrolytic hydrogen production.
