Electrochemical impedance spectroscopy spectra measured at 700 °C on porous SrTi0.30Fe0.70O3-d oxygen electrodes sintered at different temperatures

This dataset contains results electrochemica impedance spectroscopy (EIS) of symmetrical cells with porous SrTi0.30Fe0.70O3-d oxygen electrodes sintered at different temperaturs (800 °C, 900 °C and 1000 °C). EIS spectra were measured at 700 °C with synthetic air flow (21% O2, 40 ml min-1). Results converted to electrode surfaces area and dived by two electrodes.
