    Synthesis of Ru-doped double perovskite anode for SOFC
    2017 - MONTEIRO, N.K.; CANDIDO, G.A.S.; FONSECA, F.C.
    Pr0.5Ba0.5MnO3 was studied as the precursor phase of the double perovskite PrBaMn2O5+δ (PBMO) anode material for solid oxide fuel cells (SOFC). The general properties were studied in both the pristine compound and Ru-doped samples Pr0.5Ba0.5Mn1-xRuxO3 (PBMRu). Ru substitution at the B-site is expected to enhance the catalytic properties of the ceramic towards ethanol or methane fuels. The studied compounds were synthesized by the polymeric precursor method and characterized by thermogravimetric analyses, X-rays diffraction (XRD), and electrical transport properties. The experimental data show PBMO phase formation occurring at ~800°C and single phase compounds at ~1100°C up to ~10 at.% of Ru substituted. Similar ionic radius of Ru3+ and Mn3+ results in little effect on both the crystalline structure and electrical conductivity as compared to the pristine compound.
