摘要
The layered perovskite GdBaCo2O5 (+ delta) (GBCO), recently proposed for intermediate temperature solid oxide fuel cell applications, was investigated and compared with Ba0.5Sr0.5Co0.8Fe0.2O3 (-) (delta) (BSCF) cathode material using La(0.9)A(0.1)Ga(0.8)Mg(0.2)O(2.85) (A=Sr,Ba) as electrolytes. Area-specific resistance was measured by impendance spectroscopy in symmetrical cells. The cobaltites were prepared by a modified citrate sol-gel route and tested as cathode materials for
