SrMo_0.9O_3-δ Perovskite with Segregated Ru Nanoparticles Performing as Anode in Solid Oxide Fuel Cells.

ABSTRACT: A new anode material, Ru-SrMo_0.9O_3-δ, with a perovskite structure and segregated metallic Ru, has been tested in an intermediate-temperature solid oxide fuel cell (IT-SOFC) in an electrolyte-supported configuration giving substantial power densities as high as 840 mW/cm² at 850 °C using pure H₂ as fuel. This material has been prepared by the citrate method and structurally and microstructurally characterized at room temperature by different techniques such as X-ray diffraction (XRD), neutron powder diffraction (NPD), scanning electron microscopy (SEM), and scanning transmission electron microscopy (STEM). NPD was very useful to determine oxygen positions and vacancies, unveiling a cubic and oxygen-deficient perovskite SrMo_0.9O_3-δ<
