Abstract

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 Gd_0.2Ce_0.8O_1.8 (GDC) electrolyte. The electrical conductivities of Ba₂PrMoO₆ and Ba₂NdMoO₆ were 348.5 and 146 Scm⁻¹ 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.
