1. Introduction
Galvanic cells, also known as voltaic cells, represent a fundamental concept in electrochemistry, where chemical energy is converted into electrical energy through spontaneous redox reactions. These cells are pivotal in understanding not only the principles of electrochemical processes but also in practical applications ranging from batteries to corrosion prevention. The operation of galvanic cells relies on two distinct half-reactions, one involving oxidation and the other involving reduction, which occur in separate compartments. The flow of electrons between these compartments through an external circuit generates an electric current, while the movement of ions within the cell maintains charge neutrality. In a typical galvanic cell, a metal electrode is immersed in a solution of its ions, thereby establishing a half-cell. At the anode, oxidation occurs, resulting in the release of electrons. This metal electrode loses electrons and, correspondingly, metal ions e
