Résumé

GdBaCo₂O_5+x (GBCO) was evaluated as a cathode for intermediate-temperature solid oxide fuel cells. A porous layer of GBCO was deposited on an anode-supported fuel cell consisting of a 15 μm thick electrolyte of yttria-stabilized zirconia (YSZ) prepared by dense screen-printing and a Ni-YSZ cermet as an anode (Ni-YSZ/YSZ/GBCO). Values of power density of 150 mW cm^-2 at 700 °C and ca. 250 mW cm^-2 at 800 °C are reported for this standard configuration using 5% of H₂ in nitrogen as fuel. An intermediate porous layer of YSZ was introduced between the electrolyte and the cathode improving the performance of the cell. Values for power density of 300 mW cm^-2 at 700 °C and ca. 500 mW cm^-2 at 800 °C in this configuration were achieved.
