Comprehending the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current propels a chemical reaction. This reaction utilizes an electrolyte membrane, frequently a solid polymer, to separate the reactants into positively charged and negatively charged chambers. The flow of ions through this membrane enables the oxidation and reduction reactions, ultimately producingboth hydrogen and oxygen.
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 variation in electrical potential initiates the migration of ions through the membrane.
- Within the anode, oxidation occurs, where a substance donates electrons. The electrons migrate through the external circuit, generating an electric current.
- Simultaneously, at the cathode, reduction happens. A substance gains electrons, leading to a chemical transformation.
