Comprehending the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current propels a chemical reaction. This reaction involves an electrolyte membrane, commonly a solid polymer, to partition the reactants into anodic and anodic chambers. The passage of ions through this membrane promotes the oxidation and reduction reactions, ultimately producingoxygen.
The fundamental 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 difference in electrical potential causes the migration of ions across the membrane.
- Upon the anode, oxidation occurs, where a substance donates electrons. The electrons travel through the external circuit, creating an electric current.
- Conversely, at the cathode, reduction occurs. A substance receives electrons, resulting in a chemical transformation.
