Model-assisted identification of solid oxide cell elementary processes by electrochemical impedance spectroscopy measurements

Jan Van Herle, Stefan Diethelm, Arata Nakajo, Priscilla Caliandro

Electrochemical Impedance Spectroscopy (EIS) is extensively used to characterize Solid Oxide Cells (SOCs) to extract information on the elementary loss mechanisms. However, these individual mechanisms usually overlap in the frequency domain, requiring dedi ...
