Comprehending the Principles of PEM Electrolysis
PEM electrolysis encompasses process where an electric current propels 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 facilitates the oxidation and reduction reactions, eventually producingboth hydrogen and oxygen.
The primary principles of PEM electrolysis revolve around the movement of charged particles. When an electric current is applied the system, it creates a potential difference between the two chambers. This variation in electrical potential causes the migration of ions across the membrane.
- Upon the anode, oxidation occurs, where a substance transfers electrons. The electrons travel through the external circuit, generating an electric current.
- Conversely, at the cathode, reduction happens. A substance accepts electrons, leading to a chemical transformation.
