New anode materials for IT-SOFC derived from the electrolyte BaIn0.3Ti0.7O2.85 by lanthanum and manganese doping

New perovskite oxides, Ba0.5La0.5Ti0.3Mn0.7O3 (BLTM) and Ba0.5La0.5In0.3Ti0.1Mn0.6O3 (BLITIM), were investigated as new anode materials that are compatible with BIT07 electrolyte. At 700 °C under air, BLTM and BLITIM exhibit a total conductivity of 13.4 and 11.7 S ∙ cm− 1 correspondingly. Under reducing atmosphere, total conductivity decreases to 0.3 and 0.6 S ∙ cm− 1 respectively. Anode-supported symmetrical cells Ni-BLTM/BIT07 and Ni-BLITIM/BIT07 were prepared by tape casting and co-sintering. An anode area specific resistance of 0.11 Ω cm2 at 700 °C was reached for an initial NiO content (40 wt.%) which is much lower than that used in Ni/BIT07 cermets (50% wt.%).
