Functional thin films as cathode/electrolyte interlayers: a strategy to enhance the performance and durability of solid oxide fuel cells

The data includes: XRD data of Sm0.2Ce0.8O1.9-La0.8Sr0.2MnO3-δ thin films Electrochemical impedance spectra of symmetrical cells with SDC and LSM thin films at 750 ºC Electrochemical impedance spectra of anode-supported cell with SDC and LSM thin films at 750 ºC Durability test of anode-supported cell with SDC and LSM thin films at 750 ºC for ca. 1500 h Electrochemical characterization (i-v and i-p curves) of anode-supported cell with SDC and LSM thin films during durability test.
