Process intensification: An electrochemical perspective

Abstract: This paper provides a review of a range of process intensification methods which have been applied to electrochemical processes and reactions. The electrochemical reactions include those in electrolysers where gas evolution occurs, in metal deposition reactions and reactions occurring in fuel cells and batteries. The process intensification methods include the use of centrifugal force fields, ultrasonics, rotating electrodes and rotating cells which operate with and without the application of magnetic fields. Such devices can be used in principle to carry out electrolysis without the application of an external potential or current. Other methods considered include the use of light. The area of magnetic field induced fluid flow is also discussed which has applications in lab on a chip technologies. The area of process intensification has largely focused a lot on hydrogen generation as a means of providing a clean, sustainable fuel.
