Nanostructured composite powder, consisting of 20 wt % SnO2, 50 wt % NiO, and 30 wt % Gd0.1Ce0.9O2 (GDC), was prepared using a combustion chemical vapor deposition process from a single solution containing all precursors. Bilayer solid oxide fuel cells (SOFC) anodes of different porosity were fabricated by copressing of NiO-GDC powder and SnO2-NiO-GDC composite powder. Porosity variation in the anodes was achieved by the removal of the SnO2-phase during firing and subsequent cell testing. Anode-supported SOFC single cells were constructed and tested for electrochemical performance. Interfacial polarization resistances of a cell with the bilayer anode were 1.20, 0.49, 0.22, and 0.1 Omega cm(2) at 500, 550, 600, and 650 C, respectively, demonstrating peak power densities of 171, 301, 441, and 544 mW/cm(2), respectively.
