In some embodiments, a solid oxide fuel cell comprising an anode, an electrolyte, cathode barrier layer, a nickelate composite cathode separated from the electrolyte by the cathode barrier layer, and a cathode current collector layer is provided. The nickelate composite cathode includes a nickelate compound and second oxide material, which may be an ion conductor. The composite may further comprise a third oxide material. The composite may have the general formula (Ln_uM1_vM2_s)_n+1(Ni_1-tN_t)_nO_3n+1-A_1-xB_xO_y--C._wD_zCe_(1-w-z)O_2-δ, wherein A and B may be rare earth metals excluding ceria.
