Grasping the Principles of PEM Electrolysis
PEM electrolysis encompasses process where an electric current propels a chemical reaction. This reaction utilizes an electrolyte membrane, commonly a solid polymer, to separate the reactants into anodic and anodic chambers. The flow 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 difference in electrical potential initiates the migration of ions across the membrane.
- At 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 accepts electrons, producing a chemical transformation.
The efficiency and performance of PEM electrolysis are influenced by a number of factors, including the type of membrane used, the concentration of electrolytes, and the operating temperature.
