| Popis: | International audience; This article presents elaboration of electrolyte-supported solid oxide fuel cells based on the oxide ion conductor BaIn0.3Ti0.7O2.85 (BIT07) as electrolyte, the amorphous reduced phase of La2Mo2O9 (La2Mo2O7-y) as anode which presents a mixed ionic and electronic conduction in low pO2 and La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF) as cathode. Electrode materials have been deposited by screen-printing on BIT07 substrate. In order to avoid chemical reactivity between BIT07 and La2Mo2O9, a thin layer of Ce0.9Gd0.1O1.95 (CGO) has been used. Electrochemical performance of the single cell has been characterized by I–V measurements and impedance spectroscopy. Encouraging performance of 40 mW cm−2 at 700 °C is obtained with a thick electrolyte layer. Finally, ageing test of the cell at 700 °C during 800 h has been done with a low rate of performance loss of 4.4 × 10−3% h−1. No degradation of the electrolyte material is reported and stability of the anode material after operating the fuel cell is discussed. |
