I recently came across literature that analyzes degradation in a solid oxide electrolysis cell using something called ADIS plots. (Analysis of the differences in impedance spectra). I am a bit confused on why such a analysis is required when similar information can be gathered from a bode plot.
Why is the impedance reported in such way?

Dear friend Srinivas Sriram
ADIS plots are used to study degradation in solid oxide electrolysis cells (SOEC) because they provide more information than a bode plot. ADIS plots are used to analyze the differences in impedance spectra and can be used to identify the cause of degradation (Performance and degradation...).
I found two papers that might be helpful for you. The first paper studies the poisoning of solid oxide electrolysis cells by impurities (Solid oxide electrolysis cell analysis...). The second paper studies the durability of solid oxide electrolysis cells for syngas production (Performance and degradation of an SOEC...).
