Due to its high ionic conductivity level, BaIn0.3Ti0.7O2.85 (BIT07) is a potential electrolyte material for SOFC. In order to validate the use of this material, its chemical, mechanical and electromechanical compatibilities with three classical cathode materials (La0.7Sr0.3MnO3 – δ (LSM), La0.58Sr0.4Co0.2Fe0.8O3 – δ (LSCF) and Nd2NiO4 + δ) have been tested. The chemical compatibility has been demonstrated by XRD experiments, which show that BIT07 does not react with the cathode materials below 1,000 °C. The mechanical compatibility has been investigated by combining measurements of the thermal expansion coefficients of the cathode materials from X‐ray thermo diffraction and SEM observations. Symmetrical cells cathode/electrolyte/cathode have been studied by electrochemical impedance spectroscopy in order to quantify the quality of the cathode/electrolyte interface and to study the long‐term stability of the cell. The main conclusion of the study is that LSCF presents the best compromise between an acceptable mechanical compatibility and very good electrical properties with BIT07.

“…Due to its high oxygen ion conductivity below 700°C, BaIn 0.3 Ti 0.7 O 2.85 (BIT07) is regarded as a potential electrolyte material for SOFC [6]. Nevertheless, this material must be compatible with usual cathode materials, and the quality of the interfaces must be excellent, even after long-term cycleability.…”

“…In a previous study, the solid state reaction synthesis of BIT07 is realized with two 24 h thermal treatments (the first one at 1200°C and the second one at 1350°C), 8 then the powder is ball-milled for 60 h at 500 rpm to obtain a submicronic powder, a tape is realized with this powder and sintered at 1300°C for 9 h to obtain a dense electrolyte. 9 Anode-supported half cells (electrolyte/anode), based on BIT07/BIT07-Ni have been prepared by tape casting and co-sintered.…”

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 lm. The anodes were porous and no obvious reaction was found between NiO and the precursors of BIT07. *marika.letilly@cnrs-imn.fr

“…However, it has never been processed as thin films. 18 In the present work, the possibility of obtaining dense BIT07 thin film onto a cheaper Ni-YSZ anode support was explored, taking in account to scale up the size, for a potential commercially viable option for SOFC applications. Further, the science and technology behind the processing technique are also discussed in detail to facilitate the adaption of this process for being low cost; hence, suitable for implementation in the streamline production process in industrial fabrication.…”

BaIn0.3Ti0.7O2.85 (BIT07) is a promising electrolyte for solid oxide fuel cells, due to its chemical compatibility with most of the cathode electrode material such as LSM and Ln2NiO4. The present work is aimed on the fabrication of anode‐supported half cells with thin BIT07 electrolyte. For this, Ni‐8YSZ cermet was chosen due to its excellent mechanical and electrochemical properties, in addition to its low cost. The NiO–8YSZ anode support was prepared by tape casting, and for this, an organic slurry formulation was optimized. The BIT07 electrolyte thin film was deposited through screen printing on the green anode. The formulation of the ink was optimized, and sintering at 1350°C for 3 h led to a dense electrolyte with controlled thickness varying from 2 to 12 μm. Further, the cermet electrode still had a homogeneous microstructure with well‐defined anode/electrolyte interface. The electrode ASR was about 0.5 Ω cm2 and was stable over 500 h at 800°C under H2–3% H2O. The fabrications of half cells were successfully scaled up to 100 mm × 100 mm retaining the dimensional control and without any surface defects.
