Comprehending the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current stimulates a chemical reaction. This reaction employs an electrolyte membrane, commonly a solid polymer, to partition the reactants into anodic and negatively charged chambers. The passage of ions through this membrane enables the oxidation and reduction reactions, consequently producingoxygen.
The fundamental principles of PEM electrolysis revolve around the movement of charged particles. When an electric current flows across the system, it creates a potential difference between the two chambers. This gap in electrical potential drives the migration of ions within the membrane.
- At the anode, oxidation occurs, where a substance loses electrons. The electrons flow through the external circuit, creating an electric current.
- Conversely, at the cathode, reduction occurs. A substance gains electrons, leading to a chemical transformation.
