| Résumé |
|
It has been demonstrated that BaIn0.3Ti0.7O2.85 (BIT07) can be used as electrolyte material in complete intermediate temperature solid oxide fuel cells (IT SOFC), associated with LSCF as cathode material and BIT07-Ni cermet as anode material. Based on those materials, button cells (empty set = 10 mm) have been designed. Using electrochemical measurements, the resistance of each part of the complete cell has been minimized, and the optimization of the complete fuel cell has been achieved. A maximum power density of about 266 mW cm(-2) at 700 degrees C under wet H-2 on the anode side and air on the cathode one has been reached, with a total area specific resistance of about 0.87 Omega cm(2) at 700 degrees C. Using impedance measurements, the total resistance of the cell has been decomposed in several parts, attributed to the different components of the cell. (C) 2011 Elsevier B.V. All rights reserved.
