【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35μm,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]:Common flow forming, In order to improve the electrochemical activity, Ni-SSZ active anode was introduced between the supporting anode and the electrolyte film in order to improve the electrochemical activity. The thickness of the active anode was adjusted by adjusting the thickness of the active anode. The anodic activity was optimized by the mass ratio of SSZ:NiO. The porosity of the supporting anode was optimized by comparing the properties of the supporting anode with different content of pore-forming agent. The results showed that the anode activity was the best when the active layer thickness was 35 渭 m, the mass ratio was 1: 1 and the propping layer pore-making agent content was 10 wt%. The maximum power density of the single cell is 0.96W / cm ~ 2 at 750 鈩，
