[Abstract]
Fundamentals of Electrochemical Impedance Spectroscopy
and its Application in Energy Issues
Digby D.
Macdonald
Distinguished
Professor of Materials Science and Engineering
Department of Materials Science and Engineering
Pennsylvania State
University
In this talk, I will review the fundamentals of electrochemical
impedance spectroscopy (EIS), identifying the advantages and pitfalls and
highlighting errors that I have seen after reviewing many manuscripts for
peer-reviewed journals. Of course, the authors will remain anonymous. I will
then illustrate the application of EIS in characterizing the electrochemical
processes that occur in the dissolution of lithium and aluminum in concentrated
alkaline solutions and the hydrogen electrode reaction on platinum
electrocatalysts. Finally, I will describe the use of EIS to characterize
porous, electronically conductive (Ebonite) noble metal catalyst supports for
the oxygen electrode reaction of the type being considered in fuel cells. The
power power of EIS in exploring electrochemical processes will be illustrated by
Reaction Mechanism Analysis.
