The technological feasibility of applying electrophoretic deposition to solid oxide fuel cells was investigated by making small tubular cathode substrates and cathode/electrolyte/anode multilayers. A small tube made of La{sub x}MnO{sub 3{+-}d}(LM), (La{sub 0.7}Sr{sub 0.3}){sub 0.9}MnO{sub 3{+-}d}, or (La{sub 0.85}Sr{sub 0.15}){sub 0.95}MnO{sub 3{+-}d} was obtained by depositing lanthanum manganite on graphite from an iodine added acetone bath or an isopropanol bath. The graphite was oxidized and removed during sintering, resulting in a tubular LM with one end closed. A multilayer consisting of porous LM/dense YSZ/porous NiO-YSZ was obtained by deposition of yttria-stabilized zirconia on presintered LM and subsequent codeposition of NiCO{sub 3} powder and YSZ powder on the YSZ-deposited LM. Finally, this LM(presintered)/YSZ(as-deposited)/NiCO{sub 3}-YSZ(as deposited) layer was cofired.
