Abstract

The purpose of this SOP is to describe a method for electrochemical impedance spectra (EIS) measurement of single solid oxide cells. By measuring the impedance response to frequency change, kinetics about ohmic and electrolyte/electrode interface transport with different time constants can be separated and attained.
