Abstract

Mixed conducting LaNi_0.6Fe_0.4O₃-δ electrode was combined with an ionically conducting oxide Ce _0.9Gd_0.1O_1.95, 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 _0.6Fe_0.4O₃-δ film electrode coated with a Ce_0.9Gd_0.1O_1.95 porous layer on the top. It showed higher ASC compared to the bare LaNi_0.6Fe_0.4O ₃-δ film electrode.
