AbstractA novel method for fabricating Ni(NO3)(2) solution impregnated YSZ (YSZ: Yttria Stabilized Zirconia) anodes for solid oxide fuel cells (SOFCs) is presented. In order to reduce the impregnation cycles and increase the reliability of the YSZ membrane, a YSZ support with a porosity of similar to 60% is soaked in a saturated Ni(NO3)(2) solution with an increased temperature of 80 degrees C. The impregnated anode is dried in a vacuum drying device without heating, resulting in a flower-like Ni(NO3)(2)center dot 6H(2)O crystal. The formed porous structure is likely to facilitate the impregnating process and considered to be the key to success of the impregnation process with saturated solution. After heating at 700 degrees C, a novel needle-shaped NiO is presented, which exhibits some advantages including fast preparation, high connectivity, large specific surface area and high operational stability (i.e. high aggregation resistance). For the purpose of comparison, Ni(NO3)(2) solution impregnated YSZ anodes prepared through the conventional impregnation process are also characterized under the same conditions.
