Understanding the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current drives a chemical reaction. This reaction employs an electrolyte membrane, frequently a solid polymer, to partition the reactants into anodic and negatively charged chambers. The movement of ions through this membrane enables the oxidation and reduction reactions, consequently producinghydrogen.
The core 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 through the membrane.
- Within the anode, oxidation occurs, where a substance transfers electrons. The electrons migrate through the external circuit, creating an electric current.
- Conversely, at the cathode, reduction occurs. A substance gains electrons, resulting in a chemical transformation.
