Grasping the Principles of PEM Electrolysis
PEM electrolysis is a process where an electric current stimulates a chemical reaction. This reaction utilizes an electrolyte membrane, frequently a solid polymer, to separate the reactants into positively charged and anodic chambers. The passage of ions through this membrane facilitates the oxidation and reduction reactions, ultimately producinghydrogen.
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 two chambers. This gap in electrical potential causes the migration of ions across the membrane.
- At the anode, oxidation occurs, where a substance loses electrons. The electrons migrate through the external circuit, producing an electric current.
- In contrast, at the cathode, reduction takes place. A substance accepts electrons, resulting in a chemical transformation.
