In the present thesis targeted modifications with Au, MoOx and FexOy were applied on commercially available NiO/GDC (65 wt.% NiO – 35 wt.% Ce0.9Gd0.1O2-x) cermet, by means of deposition precipitation and deposition co-precipitation. Extensive physicochemical characterization was performed for the pr...
