Procedures for the synthesis of nanocomposite anode materials comprised of Ni-YSZ promoted by doped Ce-Zr-O fluorite-like or La-Pr-Mn-Cr-O perovskite-like oxides and Pt/Ru were elaborated. Their composition, structure, reactivity, and catalytic properties in CH4 steam reforming were characterized using various techniques, such as SEM, TEM, EDX, TPR, and I-V testing in SOFC conditions. The optimized nanocomposites supported on compressed foam Ni-Al substrates demonstrated high and stable performance at H2O:CH4=1:2 ratio without coking or sintering. For the SOFC testing, the planar catalytic substrates with the surface area of 5x5 cm2 have been used. The demonstrated SOFC performance in the internal CH4 reforming mode was close to the performace obtained with the humidified hydrogen. The achieved power density was up to 300-800 mW/cm2 at 600-800 oC meeting the targets of the area specific resistance, fuel effficiency, and power density.
