    Fractal analysis of surface topography of solid oxide fuel cell materials
    (Видавництво Львівської політехніки, 2012) Suchaneck, G.; Ponomareva, A. A.; Brychevskyi, M.; Brodnikovskyi, I.; Vasylyev, O.; Gerlach, G.
    In this work, we investigate the hierarchical surface topography of solid oxide fuel cell electrolytes consisting of zirconia stabilized with 10% Sc2O3 and 1% CeO2 (1Ce10ScSZ) synthesized at 1300-1400 °C and anodes of 60 wt% 1Ce10ScSZ and 40 wt% NiO synthesized at 1250 to 1550 °C. The fractal dimension of AFM images of the films was determined by the cube counting method, the triangulation method and by means of the PSD slope at large wavenumbers. RMS roughness and correlation lengths were derived from the fit to the model PSD.
