Resumo
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.
