Understanding the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current drives a chemical reaction. This reaction utilizes an electrolyte membrane, typically a solid polymer, to separate the reactants into positively charged and negatively charged chambers. The flow of ions through this membrane promotes the oxidation and reduction reactions, ultimately producingboth hydrogen and oxygen.
The primary principles of PEM electrolysis center on the movement of charged particles. When an electric current is applied the system, it creates a potential difference between the two chambers. This gap in electrical potential causes the migration of ions across the membrane.
- Upon 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 receives electrons, producing a chemical transformation.
