This paper presents results of research aimed at development of efficient synthesis procedirres and characterization of oxide-ion conducting electrolytes based on doped lanthanum sihcate with the apatite stiuctirre promising for design of solid oxide fuel cells operating at intermediate temperatirres. Phase-pure nanocrystalline powders of doped... 

Approaches to design of cathode and anode materials for solid oxide fuel cells with the apatite-type electrolyte compatible by thermal expansion and chemical tolerance were elaborated. For cathodes, nanocomposites comprised of complex Ni-containing perovskites and Fe-doped La silicate were found to be promising materials due to chemical compatibility and non-additive increase of both reactivity in O2 activation and oxygen mobility due to...
