Comprehending the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current drives a chemical reaction. This reaction involves an electrolyte membrane, frequently a solid polymer, to partition the reactants into cathodic and cathodic chambers. The flow of ions through this membrane promotes the oxidation and reduction reactions, ultimately producingoxygen.
The core principles of PEM electrolysis pivot upon 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 drives the migration of ions within the membrane.
