Understanding the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current stimulates a chemical reaction. This reaction involves an electrolyte membrane, commonly a solid polymer, to divide the reactants into cathodic and cathodic chambers. The movement of ions through this membrane promotes the oxidation and reduction reactions, consequently producingoxygen.
The core principles of PEM electrolysis center on the movement of charged particles. When an electric current flows across the system, it creates a potential difference between the two chambers. This variation in electrical potential drives the migration of ions within the membrane.
- Upon the anode, oxidation occurs, where a substance loses electrons. The electrons migrate through the external circuit, generating an electric current.
- Conversely, at the cathode, reduction happens. A substance receives electrons, leading to a chemical transformation.
The efficiency and performance of PEM electrolysis are determined by a number of factors, including the type of membrane used, the concentration of electrolytes, and the operating temperature.
