چکیده انگلیسی
Ba2LnMoO6 (Ln = Pr and Nd), with a double perovskite structure, has been investigated as an efficient anode material for solid oxide fuel cells (SOFCs) operating under methane fuel. Ba2LnMoO6 (Ln = Pr and Nd) powders were successfully synthesized by a citric acid ethylene-diamine-tetraacetic acid (CA-EDTA) combustion technique. Ba2LnMoO6 (Ln = Pr and Nd) was thermally and morphologically stable at high temperature and chemically compatible with the Gd0.2Ce0.8O1.8 (GDC) electrolyte. The electrical conductivities of Ba2PrMoO6 and Ba2NdMoO6 were 348.5 and 146 Scmâ1 under humidified CH4 at 800 °C, respectively. However, Ba2LnMoO6 (Ln = Pr and Nd) exhibits better catalytic activity for the hydrogen oxidation reaction (HOR) than for the methane oxidation reaction (MOR); this is due to the presence of deposited carbon, which blocks the fuel path during the overall methane oxidation process.
