A solid oxide fuel cell comprises a dense electrolyte disposed between a porous anode and a porous cathode wherein the dense electrolyte comprises doped lanthanum gallate or yttria stabilized zirconia, the porous anode comprises yttrium-doped strontium titanate, yttrium-doped strontium titanate and nickel, lanthanum-doped ceria and nickel or yttria stabilized zirconia and nickel and the porous cathode comprises doped lanthanum ferrite or strontium-doped lanthanum manganite. The fuel cell may further comprise an interlayer(s) comprising lanthanum-doped ceria disposed between an electrode (anode, cathode or both) and the electrolyte. An interconnect layer comprising doped lanthanum chromate may be disposed between the anode of a first single fuel cell and the cathode of a second single fuel cell. The anode, cathode, electrolyte and optional interlayer(s) are produced by thermal spray.
