Grasping the Principles of PEM Electrolysis
PEM electrolysis encompasses process where an electric current drives a chemical reaction. This reaction utilizes an electrolyte membrane, frequently a solid polymer, to separate the reactants into anodic and cathodic chambers. The flow of ions through this membrane enables the oxidation and reduction reactions, eventually producinghydrogen.
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 difference in electrical potential initiates the migration of ions within the membrane.
- At the anode, oxidation occurs, where a substance donates electrons. The electrons migrate through the external circuit, generating an electric current.
- In contrast, at the cathode, reduction takes place. A substance gains electrons, leading to 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.
