Understanding the Principles of PEM Electrolysis

PEM electrolysis encompasses process where an electric current propels a chemical reaction. This reaction involves an electrolyte membrane, commonly a solid polymer, to partition the reactants into anodic and anodic chambers. The movement of ions through this membrane promotes the oxidation and reduction reactions, eventually producingboth hydrogen and oxygen.

The core principles of PEM electrolysis center on the movement of charged particles. When an electric current passes through the system, it creates a potential difference between the two chambers. This variation in electrical potential causes the migration of ions across the membrane.

  • Within the anode, oxidation occurs, where a substance transfers electrons. The electrons migrate through the external circuit, creating an electric current.
  • In contrast, at the cathode, reduction occurs. A substance gains electrons, resulting in a chemical transformation.

The efficiency and performance of PEM electrolysis are determined by a number of factors, including the type of membrane used, the concentration of electrolytes, and the operating temperature.
