To probe the oxygen flux over an extended period of 1000 h, oxygen permeation measurements are performed at 700 degrees C for La0.6Sr0.4Co0.2Fe0.8O3-6 (LSCF) coated with K2NiF4-structure Pr4Ni3O10+6 (PNO) while varying surface coverage. The optimization of PNO surface coverage, thickness, and porosi...
