研究了以流延法成型中温平板式固体氧化物燃料电池(IT-SOFC)Ni-YSZ阳极基底金属陶瓷,并成功地制备出厚度为200-500μm的该金属陶瓷基底材料.在其中添加不同种类的成孔剂以增加孔隙率.对以该流延工艺制备的素坯及复合陶瓷的性能进行了研究,其中,素坯膜的热烧结性能通过热重-差示扫描分析进行了研究;复合陶瓷基体材料的孔隙率以阿基米德排水法进行了测试;并以扫描电子显微镜观察了其微观形貌.确定了NiO-YSZ基底材料的预烧及成瓷烧结温度范围.随着烧结温度的升高,孔隙率逐渐下降.其中,有机成孔剂和无机成孔剂在造孔性能方面还存在着某些方面的差异.

The tape cast technique was successfully used to fabricate the Ni-YSZ anode substrate cermet of planar intermediate-temperature solid oxide fuel cell (IT-SOFC), such cermets with thickness of 200 - 500 μm were prepared. Pore-formers were used to increase the porosity of the substrates. Some properties of the tape casting products were studied. The green tape was analyzed by TG-DSC analysis, the porosity of the cermets was measured with Archimedes' method, the microstructure was observed by scanning electron microscope. The pre-sintering and sintering temperature of the NiO-YSZ substrate was determined. The porosity is decrescent with the increasing sintering temperature. There are some differences between organic pore-formers and inorganic ones.
