Grasping the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current propels a chemical reaction. This reaction involves an electrolyte membrane, commonly a solid polymer, to divide the reactants into cathodic and negatively charged chambers. The movement of ions through this membrane enables the oxidation and reduction reactions, consequently producingoxygen.
The primary principles of PEM electrolysis revolve around the movement of charged particles. When an electric current passes through the system, it creates a potential difference between the two chambers. This gap in electrical potential drives the migration of ions within the membrane.
- Upon the anode, oxidation occurs, where a substance loses electrons. The electrons travel through the external circuit, creating an electric current.
- Simultaneously, at the cathode, reduction takes place. A substance gains electrons, producing a chemical transformation.
