BaIn 0.3 Ti 0.7 O 2.85 ( BIT07 )/ BIT07 ‐Ni electrolyte/anode half cell was prepared by reactive sintering for solid oxide fuel cells. The precursors were BaCO 3 , In 2 O 3 , and TiO 2 for electrolyte and BaCO 3 , In 2 O 3 , TiO 2 , NiO , and carbon black for anode. The bi‐layers were prepared by a multilayer tape casting and co‐firing method. The compositions and microstructures of the phases were studied by X ‐ray powder diffraction and scanning electron microscopy, respectively. The electrolytes were dense with pure perovskite phase with a thickness about 15 μm. The anodes were porous and no obvious reaction was found between NiO and the precursors of BIT07 .
