研究了一种新型的固体氧化物燃料电池纳米结构阳极的制备技术。通过在pH控制的水介质中混合纳米尺寸的NiO和YSZ粉末，通过杂凝聚成功地获得了纳米颗粒的精细混合物。由此制备的混合物制备的阳极具有大的三相界面，并且通过增加电导率和有效表面积而显示出阳极性能的极大改善。
A novel preparation technique for a nanostructured anode for a solid oxide fuel cell is investigated. By mixing nanometer-sized NiO and YSZ powders in a pH-controlled aqueous media, a fine mixture of nanoparticles is successfully obtained through heterocoagulation. The anode prepared from thus prepared mixture has a large triple phase boundary and shows a great improvement in the anode performance by increasing the electric conductivity and effective surface area.
