ElectrodesF 3000 Characterization of GdBaCo2O5+δ Cathode for IT-SOFCs. — The title compound

is a promising cathode candidate for intermediate temperature solid oxide fuel cells. It exhibits good chemical compatibility with the Sm0.2Ce0.8O1.9 electrolyte and has a con-ductivity of 512—290 S/cm in the temperature range 500—800 °C. The thermal ex-pansion coefficient is about 20.1·10-6 K-1 between 30 and 900 °C in air. The optimal sintering temperature is 1050 °C for 4 h. — (LI*, N.; LUE, Z.; WEI, B.; HUANG, X.; CHEN, K.; ZHANG, Y.; SU, W.; J. Alloys Compd. 454 (2008) 1-2, 274-279; Cent. Condens. Matter Sci.
