Al-Doped SrMoO₃ Perovskites as Promising Anode Materials in Solid Oxide Fuel Cells.

ABSTRACT: Two perovskite materials with SrMo_1-xAl_xO_3-δ (x = 0.1, 0.2) compositions have been synthesized by reduction from the corresponding scheelite phases, with SrMo_1-xAl_xO_4-δ stoichiometry; the pertinent characterization shows that the defective perovskites can be used as anode materials in solid oxide fuel cells, providing maximum output power densities of 633 mW/cm² for x = 0.2. To correlate structure and properties, a neutron powder diffraction investigation was carried out for both perovskite and scheelite phases. Both perovskites are cubic, defined in the Pm-3m space group, displaying a random distribution of Mo and Al cations over the 1a sites of the structu
