【摘要】：采用共流延成型、共燒結(jié)法制備了以Ni-YSZ陽極支撐的氧化鈧穩(wěn)定的氧化鋯(SSZ)電解質(zhì)膜。為提高電化學(xué)活性在支撐陽極與電解質(zhì)膜之間引入了Ni-SSZ活性陽極。通過調(diào)整活性陽極的厚度和SSZ:NiO的質(zhì)量比優(yōu)化了陽極活性;通過比較支撐陽極中添加不同造孔劑含量時(shí)的性能,優(yōu)化了支撐陽極的孔隙率。研究結(jié)果表明,當(dāng)活性層厚度為35μm,質(zhì)量比為w(SSZ):w(NiO)=1:1,支撐層造孔劑含量為10wt%時(shí),陽極活性最佳;采用絲網(wǎng)印刷并燒結(jié)LSM-SSZ復(fù)合陰極后,所得單電池在750℃的最高功率密度達(dá)到0.96 W/cm2,比優(yōu)化前本課題組前期報(bào)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，
