Grasping the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current propels a chemical reaction. This reaction utilizes an electrolyte membrane, typically a solid polymer, to separate the reactants into anodic and cathodic chambers. The passage of ions through this membrane promotes the oxidation and reduction reactions, eventually producingoxygen.
The fundamental principles of PEM electrolysis revolve around 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 through the membrane.
- At the anode, oxidation occurs, where a substance transfers electrons. The electrons migrate through the external circuit, generating an electric current.
- Conversely, at the cathode, reduction occurs. A substance receives electrons, resulting in a chemical transformation.
The efficiency and performance of PEM electrolysis are influenced by a number of factors, including the type of membrane used, the concentration of electrolytes, and the operating temperature.
