Comprehending the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current drives a chemical reaction. This reaction employs an electrolyte membrane, frequently a solid polymer, to divide the reactants into anodic and cathodic chambers. The movement of ions through this membrane enables the oxidation and reduction reactions, eventually producingoxygen.
The primary 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 difference in electrical potential drives the migration of ions through the membrane.
- At the anode, oxidation occurs, where a substance loses electrons. The electrons flow through the external circuit, creating an electric current.
