A composite bottom-up processing has been investigated for syntheses of nanocomposite particles, based on utilization of dispersion and coagulation of fine-nanosized oxide particles (<10nm). Anode and cathode electrode materials of solid oxide fuel cells (SOFC), has been synthesized by the newly developed method. It was also demonstrated that the performances of electrodes fabricated from these nanocomposite particles are enhanced due to formation of large triple phase boundary. A multiple co-precipitation method has been studied using anionic Zr carbonate complex, and it has been demonstrated that homogenous nanocomposite particles are synthesized by this method. An anode-supported SOFC with a nanostructured Ni-YSZ anode active layer was fabricated using the nanocomposite particles, and a relatively high power density wad observed.

利用氧化物细纳米颗粒（<10 nm）的分散和凝聚作用，研究了一种自下而上的复合工艺制备纳米复合颗粒。用这种新方法合成了固体氧化物燃料电池（SOFC）的正负极电极材料。研究还表明，由于形成了大的三相界面，由这些纳米复合颗粒制成的电极的性能得到了增强。研究了一种使用阴离子碳酸锆络合物的多重共沉淀方法，并证明了通过该方法合成了均匀的纳米复合颗粒。使用该纳米复合颗粒制备了具有纳米结构Ni-YSZ阳极活性层的阳极支撑固体氧化物燃料电池，并观察到相对较高的功率密度。
