Grasping the Principles of PEM Electrolysis
PEM electrolysis is 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 negatively charged chambers. The passage of ions through this membrane enables the oxidation and reduction reactions, consequently producingboth hydrogen and oxygen.
The fundamental principles of PEM electrolysis pivot upon the movement of charged particles. When an electric current passes through the system, it creates a potential difference between the two chambers. This gap in electrical potential causes the migration of ions across the membrane.
- Within the anode, oxidation occurs, where a substance transfers electrons. The electrons flow through the external circuit, producing an electric current.
- Simultaneously, at the cathode, reduction happens. A substance accepts electrons, producing a chemical transformation.
