为了改善固体氧化物燃料电池阳极的性能，采用碳酸盐共沉淀法合成了金属陶瓷阳极，并在不同温度(500℃~800℃)下焙烧。以煅烧粉末为原料，采用单轴压制法制备了球团矿。然后对这些球团进行了表征，研究了焙烧温度对其微观结构、热行为、孔隙率、碳酸盐结合以及导电性的影响。合成过程中形成的碳酸盐对Ni-SDC的性能有很大的影响。结果表明，Ni-SDC在每个过程中都保持了其化学相容性。热重分析表明，低温焙烧的样品失重较大。由于孔隙率随着焙烧时间的增加而增加，电子导电性和性能也会得到提高。
In order to improve the performance of the anode of solid oxide fuel cells, the cermet anodes were synthesized by employing a carbonate co-precipitation method and calcined at different temperatures (500 degrees C-800 degrees C). The fabrication of pellet from calcined powder was done by uniaxial pressing. These pellets were then characterized to investigate the effect of calcination temperature on their microstructure, thermal behavior, porosity, and carbonate bonding along with conductivity. The carbonates formed within the synthesis process has shown a strong effect over the properties of the Ni-SDC. It is observed that Ni-SDC maintained its chemical compatibility during each process. The thermal gravimetric analysis showed that more weight loss occurred for the specimen calcined at low temperature. Due to the porosity increases with calcination electronic conductivity and performance will also be enhanced.
