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.

已经研究了基于分散体的利用和凝结细纳米氧化物颗粒（<10nm）的纳米复合颗粒合成的复合材料自下而上处理。固体氧化物燃料电池（SOFC）的阳极和阴极电极材料已通过新开发的方法合成。还证明，由于形成大三相边界，这些纳米复合颗粒制造的电极的性能得到了增强。已经使用阴离子ZR碳酸盐复合物研究了一种多重共沉淀方法，并证明该方法合成了同质纳米复合颗粒。使用纳米复合材料颗粒制造了带有纳米结构的Ni-ysz阳极活性层的阳极支持的SOFC，观察到了相对较高的功率密度。
