Introduction
An electrochemical cell is a system in which oxidation-reduction (redox) reactions occur through the transfer of electrons between chemical species. It consists of two electrodes: an anode (the electrode where oxidation occurs) and a cathode (the electrode where reduction occurs), which are separated by an electrolyte solution that allows the flow of charged particles, typically ions.
