Grasping the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current stimulates a chemical reaction. This reaction utilizes an electrolyte membrane, typically a solid polymer, to partition the reactants into anodic and negatively charged chambers. The flow of ions through this membrane facilitates the oxidation and reduction reactions, eventually producingboth hydrogen and oxygen.
The core 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 gap in electrical potential initiates the migration of ions across the membrane.
- Within the anode, oxidation occurs, where a substance donates electrons. The electrons travel through the external circuit, generating an electric current.
- Simultaneously, at the cathode, reduction takes place. A substance receives electrons, producing a chemical transformation.
The efficiency and performance of PEM electrolysis are affected by a number of factors, including the type of membrane used, the concentration of electrolytes, and the operating temperature.
