Grasping the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current stimulates a chemical reaction. This reaction utilizes an electrolyte membrane, typically a solid polymer, to divide the reactants into cathodic and anodic chambers. The flow of ions through this membrane enables the oxidation and reduction reactions, consequently producingoxygen.
The primary principles of PEM electrolysis center on the movement of charged particles. When an electric current passes through the system, it creates a potential difference between the two chambers. This variation in electrical potential drives the migration of ions across the membrane.
- Upon the anode, oxidation occurs, where a substance loses electrons. The electrons flow through the external circuit, creating an electric current.
- Simultaneously, at the cathode, reduction happens. A substance gains electrons, resulting in a chemical transformation.
