Sm(0.)5Ba(0.5)MnO(3-delta) (SBMO) has been synthesized with the Pechini method and investigated as an anode material of solid oxide fuel cells with H-2 and methanol as fuels. A cubic perovskite structure is formed after reduction. The reduction process of SBMO is studied with X-ray photoelectron spectroscopy and temperature programmed reduction techniques. The electrical conductivities of an SBMO sample sintered at 950 degrees C are 1.15 and 0.10 S cm(-1) at 850 degrees C in air and H-2, respectively. A single cell with an SBMO anode layer and a 300-mu m La0.8Sr0.2Ga0.8Mg0.2O3-delta electrolyte layer exhibits a maximum power density (P-max) of about 150 mW cm(-2) at 850 degrees C with H-2 as fuel. The electrical conductivity of the anode layer with methanol as fuel is improved by the moderate carbon deposition, and the Pmax increases to about 415 mW cm(-2). The cell fed with methanol also shows a promising stability.
