High Oxygen Exchange Activity of Pristine La0.6Sr0.4FeO3–δ Films and Its Degradation - Dataset

LSF thin film electrodes on YSZ substrates were characterized by electrochemical impedance spectrocopy inside the pulsed laser deposition chamber and in ex-situ emasurement setups. Inside the deposition chamber (in-situ) these electrodes revealed drastically lower polarization resistances. Exposure to several potential degradation sources inside the chamber showed this to be a rather robust effect. A detaield description is available in: https://doi.org/10.1149/1945-7111/abac2b This dataset includes the measured impedance spectra. The directory structure represents the order in which the se spectra appear in the publication. Several spectra are discussed in the context of several effects (e.g pO2 dependency and time dependency). In such cases, they are (redundantly) included in both relevant subdirectories.
