Understanding the Principles of PEM Electrolysis
PEM electrolysis presents a process where an electric current stimulates a chemical reaction. This reaction involves an electrolyte membrane, frequently a solid polymer, to partition the reactants into positively charged and cathodic chambers. The passage of ions through this membrane facilitates the oxidation and reduction reactions, ultimately producingoxygen.
The core principles of PEM electrolysis center on the movement of charged particles. When an electric current is applied the system, it creates a potential difference between the here two chambers. This gap in electrical potential causes the migration of ions within the membrane.
- Within the anode, oxidation occurs, where a substance donates electrons. The electrons flow through the external circuit, creating an electric current.
- In contrast, at the cathode, reduction occurs. A substance gains electrons, producing a chemical transformation.
