PEM Pure Water Electrolyzer CCM MEA

PEM Pure Water Electrolyzer CCM MEA

Product Introduction Electrolyzer MEAs
An Electrolyzer is an electrochemical device to convert electricity and water into hydrogen and oxygen,electrolysis cell is an advanced patented product, which are 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. The SPE electrodes, as the core of cell , are highly active catalytic electrode with nearly zero distance between the electrodes , which is formed by integrating composite catalyst with and ion membrane with high electrolytic efficiency.

Working Principle:
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.

Attention:

you must make out the MEA (fuel cell MEA or PEM CCM ) , the catalyst is total different .
