Electrochemical Methods to Understand Polarization Curve Losses

1 ELECTROCHEMICAL METHODS TO UNDERSTAND POLARIZATION CURVE LOSSES 

A wide variety of steady and transient, in situ and ex situ, AC and DC methods have been developed to smdy electrochemical system behavior. To fully understand and apply these techniques requires a greater depth than the brief summary in this chapter can provide. For a more detailed explanation, the reader is referred to various texts devoted to electrochemical testing techniques, such as by Bard and Faulkner [1]. This chapter is designed to serve as an introduction to the potential techniques available to obtain a greater understanding and parameterization of the various polarization losses.

At this point it should be cautioned that the equivalent circuit approach can yield detailed information of the physicochemical processes of ohmic, mass transfer, and kinetic resistances for a given system, but it is subject to the assumptions of the equivalent circuit used. That is, the use of equivalent circuit analysis offers infinite possibilities and combinations of electrical circuits which all can be rearranged in different ways. The EIS
