Comprehending the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current propels a chemical reaction. This reaction involves an electrolyte membrane, commonly a solid polymer, to separate the reactants into anodic and negatively charged chambers. The passage of ions through this membrane enables the oxidation and reduction reactions, eventually producingoxygen.
The core principles of PEM electrolysis revolve around 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.
- At the anode, oxidation occurs, where a substance transfers electrons. The electrons travel through the external circuit, producing an electric current.
- Conversely, at the cathode, reduction takes place. A substance gains electrons, producing a chemical transformation.
