Abstract
Mixed conducting LaNi0.6Fe0.4O3-δ electrode was combined with an ionically conducting oxide Ce 0.9Gd0.1O1.95, which resulted in high area specific conductivity (ASC). The enhancement of ASC did not only depend on their volume ratio but depended on sintering temperatures as well. Besides the extension of triple phase boundary, the catalytic activity itself could also be enhanced at the junction of the two oxides. This was proven with a LaNi 0.6Fe0.4O3-δ film electrode coated with a Ce0.9Gd0.1O1.95 porous layer on the top. It showed higher ASC compared to the bare LaNi0.6Fe0.4O 3-δ film electrode.
