DEVELOPMENT OF PHYSICOCHEMICAL MODELS FOR ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY

Development of physico-chemical or process models for impedance spectr a requires consideration of the physics and chemistry associated with the specific system under investigation. In order to be useful for int erpretation of experimental data, the model must also account for the characteristics of the measurement. The procedure for development of p hysico-chemical models is reviewed, and a method is presented that can be used to identify measurement characteristics such as error structu re and degree of stationarity.
