Electrochemical cells

Electrochemical cells are devices that convert chemical energy into electrical energy or vice versa, based on the principles of electrochemistry. These cells consist of two electrodes (an anode and a cathode) immersed in an electrolyte solution, which facilitates the movement of ions. There are two main types of electrochemical cells: 1. **Galvanic (Voltaic) Cells**: - These cells convert chemical energy into electrical energy through spontaneous redox reactions.
