Abstract

Electrochemical cells often exhibit instabilities that can result in temporal current/potential oscillations or large spatial variations of reaction rate over the electrode surface. The complexity arises from the interplay of nonlinear chemical reactions and various physical processes. In this chapter, the characterization, description, and control of these temporal and spatiotemporal phenomena are reviewed. The use of recent experimental and data processing tools is illustrated with different types of self-organized behavior on single-and multielectrode systems. Development in the engineering and control of dynamical instabilities of electrochemical cells is summarized. Examples are provided for uniform and metastable pitting corrosion, electrocatalytic reactions, solid-state and polymer electrolyte membrane fuel cells, sensors, and some other solid-state electrochemical applications.
