Nanostructured La_0.75Sr_0.25Cr_0.5Mn_0.5O₃-Ce_0.8Sm_0.2O₂ Heterointerfaces as All-Ceramic Functional Layers for Solid Oxide Fuel Cell Applications.

ABSTRACT: The use of nanostructured interfaces and advanced functional materials opens up a new playground in the field of solid oxide fuel cells. In this work, we present two all-ceramic thin-film heterostructures based on samarium-doped ceria and lanthanum strontium chromite manganite as promising functional layers for electrode application. The films were fabricated by pulsed laser deposition as bilayers or self-assembled intermixed nanocomposites. The microstructural characterization confirmed the formation of dense, well-differentiated, phases and highlighted the presence of strong cation intermixing in the case of the nanocomposite. The electrochemical properties─solid/gas reactivity and in-plane conductivity─are strongly improved for both heterostructures with respect to the single-phase cons
