Abstract

The main goal of this chapter is to present an overview of electrochemical cell operations. An electrochemical cell is devices that use a spontaneous chemical reaction to produce electricity or conversely use applied electricity to bring about non-spontaneous useful chemical reactions. The electroactive species in the ionic conductor (electrolyte) through mass transport reaches the electrode surface where Faradaic and Non-faradaic Processes occurs. A Faradaic process such as redox reaction at the electrode-solution interface gives rise to reduction or oxidation reaction. Fick’s law gives the rate of diffusion of the oxidized or reduced species in terms of a concentration gradient. The electrified solution-electrode interface was modeled using Helmholtz compact layer model, Gouy-Chapman diffuse layer model, and the Stern model. Accepted definitions of certain physical quantities were also presented.
