摘要

本研究主要以刮刀成形法(Tape-casting)，來製備固態氧化物燃料電池的NiO-YSZ的支撐基材、NiO-BZCYYb (BaZr0.1Ce0.7Y0.1Yb0.1O3-δ) 的陽極作用層以及BZCYYb電解質層，再使用網印法(screen printing) 製作陰極材料Sm0.5Sr0.5CoO3-δ (SSC) 於以Tape-casting 所製作的SOFC 半電池上，而整體SOFC 單電池的架構為Substrate/BZCYYb-NiO/ BZCYYb/ SSC。陽極作用層厚度為30 μm、50 μm、60 μm 以及 80 μm 時的SOFC單電池，在700℃操作溫度的功率密度分別可得到613 mW cm-2、839 mW cm-2、930 mW cm-2以及883 mW cm-2。
此外，靜電噴塗沉積法應用在製備電解質薄膜於陽極作用層上。成功製備薄膜緻密之電解質，電解質層厚度為2 μm時的SOFC單電池，在700、600、500、400以及300℃操作溫度下的功率密度分別可得到1316 mW cm-2、1150 mW cm-2、997 mW cm-2、881 mW cm-2 以及345 mW cm-2 。

In this study, single solid oxide fuel cells were prepared using Tape-casting along with screen printing methods. Tape casting was employed to fabricate the half cell composed of NiO-YSZ substrate, NiO-BaZr0.1Ce0.7Y0.1Yb0.1O3-δ (BZCYYb) anode function layer (AFL) and BZCYYb electrolyte layers. Screen printing was used to prepare Sm0.5Sr0.5CoO3-δ (SSC) cathodes on half cells. The peak power density of obtained single cells at 700℃ changed from 613 mW cm-2, 839 mW cm-2, 930 mW cm-2 to 883 mW cm-2 as AFL thickness varied from 30, 50, 60 to 80 μm, respectively.
Electrostatic spray deposition (ESD) method was also employed to deposit films as electrolyte on anode function layer in this study. Dense electrolyte films were successfully prepared. The peak power density of obtained single cells with electrolyte thickness of 2 μm changed from 1316 mW cm-2, 1150 mW cm-2, 997 mW cm-2, 881 mW cm-2 to 345 mW cm-2 at temperature varied from 700, 600, 500, 400 to 300℃, respectively.
