Working Principle

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

2H₂O→4H⁺+4e⁻+O₂

2H⁺+2e⁻→H₂

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