Abstract
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 , , or was obtained by depositing lanthanum manganite on graphite substrate 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 powder and YSZ powder on the YSZ‐deposited LM. Finally, this LM(presintered)/YSZ(as‐deposited)/ ‐YSZ(as‐deposited) layer was cofired. © 2000 The Electrochemical Society. All rights reserved.
