On the conductivity degradation and phase stability of solid oxide fuel cell (SOFC) zirconia electrolytes analysed via XRD

The degradation of ionic conductivity in 6ScSZ and 3YSZ SOFC electrolytes was analysed via X-ray diffraction (XRD), 4-point conductivity and electrochemical impedance spectroscopy (EIS) and the results present a consistent story: in 6ScSZ subtle but reproducible changes to the phase assembly in the...
