Electrochemical impedance spectroscopy and Distribution of Relaxation Times analysis results for porous SrTi0.30Fe0.70O3-d oxygen electrode measured at 700 °C and 5% oxygen partial pressure

This dataset contains electrochemical impedance spectroscopy and Distribution of Relaxation Times analysis results for symmetrical cell with porous SrTi0.30Fe0.70O3-d oxygen electrodes sintered at 800 °C. EIS spectra were measured at 700 °C and 5% of oxygen partial pressure. Spectra of two RCPE elements from equivalent circuit , are also included. Results converted to electrode surfaces area and dived by two electrodes. For DRT analysis freely available DRTTool from the prof. Ciucci group was utilised. All measured EIS spectra were corrected for inductance prior to DRT analysis.本数据集包含于800℃烧结的多孔SrTi₀.₃₀Fe₀.₇₀O₃−δ氧电极对称电池的电化学阻抗谱（Electrochemical Impedance Spectroscopy, EIS）与弛豫时间分布（Distribution of Relaxation Times, DRT）分析结果。电化学阻抗谱的测试条件为700℃、氧分压5%。本数据集还收录了等效电路中两个RCPE元件的谱图数据。所有结果均已换算为归一化至单位电极表面积的数值，并经双电极总贡献归一化处理以得到单电极的对应参数。DRT分析采用了Ciucci教授团队开发的开源DRTTool工具完成。所有实测EIS谱在进行DRT分析前均已完成电感效应校正。
