通过制作小管状阴极衬底和阴极/电解液/阳极多层膜，研究了将电泳沉积应用于固体氧化物燃料电池的技术可行性。用加碘丙酮浴或异丙醇浴在石墨上沉积锰酸镧，得到了由La{subx}MnO{sub3+-}d}(Lm)、(La{sub0.7}sr{sub0.3}){sub0.9}MnO{sub3{+-}d}或(La{sub0.85}Sr{sub0.15}){sub0.95}MnO{sub3+-}d}组成的小管。在烧结过程中，石墨被氧化和去除，形成了一端闭合的管状LM。通过在预烧的光镜上沉积氧化钇稳定的氧化锆，然后在YSZ沉积的光镜上共沉积NiCo/YSZ粉末，得到了由多孔光镜/致密YSZ/多孔NiO-YSZ组成的多层膜。最后，共烧Lm(预烧)/YSZ(沉积时)/NiCo{sub3}-YSZ(沉积时)薄膜。
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.
