Lanthanum nickel oxide

Lanthanum nickelate may be used as cathode in SOFCs as such or in the form of composites.

Lanthanum nickelate (LaNO) may be used as a cathode for intermediate temperature solid oxide fuel cells (SOFCs). LaNO may be prepared by spray pyrolysis, combustion technique. It exhibits high oxygen tracer diffusion coefficients and high electronic conductivity. The structure is similar to that of K₂NiF₄, layers of LaNiO₃ separated by layers LaO and an arrangement of unoccupied interstitial sites.
