| Résumé |
|
BaIn0.3Ti0.7O2.85 (BIT07) is a potential electrolyte material for Solid Oxide Fuel Cells (SOFCs) due to its high ionic conductivity and its compatibility with commonly used cathode materials. By using tape casting and co-sintering shaping methods symmetrical cells BIT07-Ni/BIT07/BIT07-Ni have been prepared. In order to improve the interface between BIT07-Ni and BIT07, a thin anode functional active layer (AAL) deposited between the BIT07-Ni and BITO7 is used. The effect of this layer on the electrochemical performance of the symmetrical cells as well as the influence of an additional Ni current collecting layer deposited on the anode side are discussed in this study. It is shown that the presence of the AAL decreases the area specific resistance (ASR) of the anode/assembly by a factor of about two, and that the presence of the Ni layer slows down the ageing of the assembly.
