一种提高固体氧化物燃料电池性能的方法
摘要：
本发明涉及一种提高固体氧化物燃料电池性能的方法，属于固体氧化物燃料电池领域。其特征在于：(1)将烧制好的电池阳极用还原性气体(如氢气或Co)还原，将其阳极内的NiO-YSZ(YSZ指用钇稳定的氧化锆，下同)体系，还原为Ni-YSZ体系。由于从NiO还原为Ni，其间伴随着约25％的体积变化，因此，将烧制好电池的阳极还原后，阳极内将留下相当数量的空隙；(2)将还原后的电池阳极在待引入物质或其前驱体的溶液中进行浸渍；此时，由于阳极已被还原，结构变得比较疏松，待引入物或其前驱体很容易就被浸入整个阳极内。(3)将浸渍过的电池阳极热处理，分解前驱体，得到需要引入电池阳极的物质。
摘要（英）：

The invention relates to a method for improving the performance of solid oxide fuel batteries and belongs to the field of the solid oxide fuel batteries. The method is characterized in that: (1) the fired battery anode is deoxidized by reducing gas (such as H2 or Co), the NiO-YSZ (YSZ is zirconia which is stabilized by yttrium) system in the anode is deoxidized into a Ni-YSZ system. As NiO is deoxidized into Ni, 25 percent of volume is changed, therefore, after the anode of the fired battery is deoxidized, the quite a bit of clearance is left in the anode; (2) the deoxidized anode of the battery is immersed in the solution of to-be-introduced material or precursor solution; at the moment, as the anode is deoxidized, the structure is loosened, and the to-be-introduced material or the precursor can be easily immersed into the whole anode; (3) heat treatment is carried out on the immersed battery anode and the precursor is decomposed, thus obtaining the material needed to be introduced into the battery anode.
