Overview
ABSTRACT
The basis of an electrochemical reactor is a cell that consists of electrodes whose nature, shape, position, and surface condition significantly impact the overall energy efficiency. These two current conductors are immersed in an electrolyte; a difference in potential is applied to the terminals of the assembly. Other factors influence the selectivity of electrochemical reactions, including the control of the composition, the concentration, the temperature and the pH of the electrolyte. This article not only discusses the physical parameters of electrolysis cells; the various voltage components, the energy balance, but also the risk analysis of this process within an industrial environment.

INTRODUCTION
The system comprising electrodes, electrolytes with their operating range – and, if required, diaphragms or membranes – forms the basis of the electrochemical reactor.
