Abstract
We fabricate intermediate-temperature solid oxide fuel cells (SOFCs) with infiltrated film-like yttria-stabilized zirconia (YSZ) interlayers at the electrolyte/electrode interfaces, achieving improved electrochemical performances. A thin and conformal nanocrystalline YSZ interlayer is deposited at the interface between the infiltrated La0.8Sr0.2MnO3-? nanoparticles and the YSZ scaffold using an infiltration process. The grain sizes of the infiltrated YSZ interlayers are controlled to be in the range of 8
