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, frequently a solid polymer, to separate the reactants into positively charged and anodic chambers. The flow of ions through this membrane promotes the oxidation and reduction reactions, ultimately producinghydrogen.
The fundamental 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 donates electrons. The electrons migrate through the external circuit, producing an electric current.
