In this research, the following two projects were carried out for low-temperature operating solid oxide fuel cell which can be operated below or at 800℃ : (1) fabrication of ceramic films of highly oxide ion conducting electrolyte ; (2) preparation of electrode materials with high activities.For the first research project, a new process based on electrophoretic deposition (EPD) was proposed to fabricate electrolyte films supported by porous substrates which can be used as an electrode in the cell. The process enabled us to electrophoretically deposit ceramic powders onto non-conducting porous substrates. Dense yttria-stabilized zirconia (YSZ) films with a thickness of ca. 5μm were successfully fabricated on porous NiO-YSZ substrates by the process proposed. The ~5μm thick dense YSZ films showed maximum output power density of 2.01W/cm^2 at 800℃ with La(Sr)Co(Fe)O_3 cathode. The process was also used to fabricate bilayered YSZ and Sm_2O_3-doped CeO_2 (SDC) electrolyte films. Such bilayered electrolyte films were formed by depositing YSZ followed by SDC without any heat treatment, and then co-fired with substrates. Maximum power densities greater than 0.6 W/cm^2 were obtained at 700 ℃ for the bilayered electrolyte films consisting of ca. 4μm and ca. 1μm-thick SDC films.In the research on electrode materials, (Sr, Ce)MnO_3 perovskite compounds were studied. Although high electrical conductivities were obtained in the compounds, it became apparent that their catalytic properties were not sufficient for application to an electrode in low-temperature operating SOFC.

在这项研究中，以下两个项目是针对低温操作固体氧化物燃料电池进行的，该燃料电池可以在下方或800℃时进行操作：（1）制造高氧化物离子导电电解质的陶瓷膜； （2）制备具有高活性的电极材料。对于第一个研究项目，提出了一个基于电泳沉积（EPD）的新过程，以制造由多孔底物支撑的电解质膜，可用作细胞中的电极。该过程使我们能够将陶瓷粉末沉积到非导电的多孔底物上。厚度为Ca的浓密Yttria稳定的氧化锆（YSZ）膜。通过提出的过程在多孔Nio-sz底物上成功制造了5μm。用LA（SR）CO（Fe）O_3阴极在800°时，〜5μm厚的致密YSZ膜显示出2.01W/cm^2的最大输出功率密度。该过程还用于制造双层YSZ和SM_2O_3掺杂的CEO_2（SDC）电解质膜。这种双层电解质膜是通过沉积YSZ的，然后进行SDC形成的，而无需进行任何热处理，然后与底物共同培养。对于由Ca组成的双层电解质膜，在700℃中获得了大于0.6 W/cm^2的最大功率密度。 4μm和ca。 1μm-厚的SDC膜。在电极材料研究，（SR，CE）MNO_3钙钛矿化合物。尽管在化合物中获得了高电导率，但很明显，它们的催化特性不足以在低温工作SOFC中应用于电极。
