PEM hydrogen Technology 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.

Characteristics of QL-300B hydrogen generator:

1.Electrolysis of pure water (adding no alkali) to produce hydrogen with no corrosion and pollution, and the purity of hydrogen is extremely high.

2.Voltage of unit cell is low, and electric resistance in the electrolysis cell is little, giving out no heat, and cycle of changing desiccants is long, producing highly pure hydrogen.

3.With stable pressure and output, Hydrogen is controlled according to the requirements, and automatic control technology is perfect and reliable.

4.Power consumption is less, and the electrolysis is efficient.

5.H2 flow and pressure is stable

6.Titanium material

7.DuPont Nafion Membranes N-117
