N2 - A highly active anode material for solid oxide fuel cells resistant to carbon deposition is developed. Co-Fe co-doped La 0.5 Ba 0.5 MnO 3- with a cubic-hexagonal heterogeneous stucture is synthesized through the Pechini method. An A-site ordered double perovskite with Co 0.94 Fe 0.06 alloy-oxide core-shell nanoparticles on its surface is formed after reduction. The phase transition and the exsolution of the nanoparticles are investigated with X-ray diffraction, thermogravimetric analysis, and high-resolution transmission electron microscope. The exsolved nanoparticles with the layered double-perovskite supporter show a high catalytic activity. A single cell with that anode and a 300 μm thick La 0.8 Sr 0.2 Ga 0.8 Mg 0.2 O 3 electrolyte layer exhibits maximum power densities of 1479 and 503 mW cm -2 at 850 °C with wet hydrogen and wet methane fuels, respectively.
