Understanding the Principles of PEM Electrolysis
PEM electrolysis encompasses process where an electric current stimulates a chemical reaction. This reaction employs an electrolyte membrane, commonly a solid polymer, to divide the reactants into cathodic and anodic chambers. The passage of ions through this membrane promotes the oxidation and reduction reactions, ultimately producingboth hydrogen and oxygen.
The primary principles of PEM electrolysis pivot upon the movement of charged particles. When an electric current flows across the system, it creates a potential difference between the two chambers. This gap in electrical potential drives the migration of ions through electrolyzer manufacturers the membrane.
- Upon the anode, oxidation occurs, where a substance transfers electrons. The electrons flow through the external circuit, creating an electric current.
- Conversely, at the cathode, reduction happens. A substance gains electrons, resulting in a chemical transformation.
