Resumen:
The Focused Ion Beam (FIB) technique was used to prepare site-specific samples from interfacial regions of different solid oxide fuel cells assemblies. Transmission and Scanning Electron Microscopy on the FIB foils combined with Electrochemical Impedance Spectroscopy (EIS) allowed the characterization of the electrode/electrolyte interphases and the determination of its influence on the cell performance after long-term operation conditions. This work reviews two cases: on one hand, Ln2NiO4+d (Ln= La, Nd) cathodes deposited on both Y0.08Zr0.92O1.96 and Ce0.9Gd0.1O1.95 electro-
