Overview

An electrochemical cell is a device capable of either harnessing electrical energy generated from chemical reactions within it or using externally supplied electrical energy to drive chemical processes. These devices exhibit the unique ability to convert chemical energy into electrical energy and, conversely, to facilitate chemical reactions using electrical energy. The two main types of electrochemical cells are galvanic (voltaic) cells and electrolytic cells. Galvanic (Voltaic) cells convert chemical energy into electrical energy. They are commonly found in batteries. The electrons produced by the chemical reaction flow through an external circuit, creating an electric current. Electrolytic Cells are non-spontaneous electrochemical devices that require an external electrical energy source to drive a chemical reaction. Both types of electrochemical cells consist of two electrodes (conductors where the electrical current enters and exits the cell) and an electrolyte (a substance that facilitates the movement of ions between the electrodes). In the DEEP group, we are currently studying and developing electrochemical cells including fuel cells, electrolyzers, and batteries.
