Understanding the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current drives a chemical reaction. This reaction employs an electrolyte membrane, frequently a solid polymer, to partition the reactants into cathodic and negatively charged chambers. The flow of ions through this membrane facilitates 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 is applied 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 migrate through the external circuit, generating an electric current.
- In contrast, at the cathode, reduction occurs. A substance gains electrons, resulting in a chemical transformation.
