摘要/Abstract

摘要： 采用共流延成型、共烧结法制备了以Ni-YSZ阳极支撑的氧化钪稳定的氧化锆(SSZ)电解质膜。为提高电化学活性在支撑阳极与电解质膜之间引入了Ni-SSZ活性阳极。通过调整活性阳极的厚度和SSZ:NiO的质量比优化了阳极活性; 通过比较支撑阳极中添加不同造孔剂含量时的性能, 优化了支撑阳极的孔隙率。研究结果表明, 当活性层厚度为35 μm, 质量比为w(SSZ):w(NiO)=1:1, 支撑层造孔剂含量为10wt%时, 阳极活性最佳; 采用丝网印刷并烧结LSM-SSZ复合阴极后, 所得单电池在750℃的最高功率密度达到0.96 W/cm², 比优化前本课题组前期报道的性能提高了2.3倍。

Abstract: The scandia-stabilized zirconia (SSZ) electrolyte supported by Ni-YSZ anode was prepared by tape casting and co-firing techniques. In order to improve the electrochemical activity, a Ni-SSZ anode active layer was introduced between the supporting anode and the electrolyte film. The anode activity was optimized by adjusting the thickness and mass ratio of SSZ: NiO in the active layer. The pore distribution and porosity of supporting anode were optimized by comparing the performance of cells with different content of pore former in the supporting anode. As a result, the thickness of active layer was optimized to be 35 μm, with w(SSZ):w(NiO)=1:1, and 10wt% carbon as anode pore former. The composite cathode of LSM-SSZ was prepared by screen printing and sintering method, and the maximum power density of single cell as high as 0.96 W/cm² was obtained at 750℃. The performance was about 2.3 times higher than what previously reported by our group.
