Abstract
The perovskite with nominal composition LaNi0.6Co0.4O3 was evaluated f or the use as a possible solid oxide fuel cell (SOFC) cathode. Thick f ilm layers, printed and fired on yttria stabilised zirconia (YSZ) elec trolyte, exhibit good characteristics, i.e. a porous microstructure, a temperature expansion coefficient of 11.9 X 10(-6)/K, and low, temper ature independent, sheet resistivity. However, LaNi0.6Co0.4O3 reacts w ith YSZ at lower temperatures than other perovskites which are usually used for SOFC cathodes.
