本研究利用生胚(Green tape)及層疊共燒(Co-sintering)，製備尺寸為10 × 10 cm2之中溫型固態氧化物燃料電池片(Intermediate temperature-solid oxide fuel cell, IT-SOFC)，全電池組態為NiO+8YSZ陽極支撐層/NiO＋8YSZ陽極層/ScSZ電解質層/10GDC陰極阻障層/LSC陰極層，透過對製作參數如生胚厚度、燒結溫度等的調整進行對IT-SOFC電性的測試。
大尺寸平板陽極支撐型SOFC電池片，主要利用刮刀成型機及網版印刷機等設備製作用以確保所製備電池片具製作穩定性及良好電性。生胚共燒製作完成的陽極半電池(Half cell)基板，利用光學非接觸式平面度量測儀及機械萬能測試機進行基板平面度及強度測試。結果顯示各層生胚於燒結時的收縮不同導致基板翹曲，而翹曲產生源於限制燒結(Constraint sintering)，其程度可藉由陽極支撐層厚度作調整；不同厚度的半電池基板，於三點抗折的強度表現大致相同，但可承受的最大壓強隨厚度增加而加大。
以網版印刷製程在陽極半電池基板上逐層製作並燒結陰極阻障層(10GDC)及陰極層(LSC)，將此單電池封裝並利用電化學分析儀進行測量。陽極端通入氫氣，陰極端通入空氣，操作溫度範圍設定在650℃-750℃之間，研究氣體流量的差異、操作溫度的不同、陽極支撐層厚薄及不同半電池燒結溫度對於電性表現的影響。結果顯示隨其體流量增加及操作溫度上升，電流密度及電功率密度皆呈現上升趨勢；而隨陽極支撐層厚度下降及半電池燒結溫度提高電性達最高，於750℃下運行8小時後電流可高達103.27 A，最高電功率密度為892.70 mW/cm2。實驗結果說明以量產設備及手法所製備的SOFC電池片，除具量產性及良好燒結良率外，還能夠於中溫操作條件下有良好的電性表現。

In this study, tape casting and co-sintering processes were utilized to prepare Intermediate Temperature-Solid Oxide fuel cell (Fuel Cells) (IT-SOFCs) with dimensions of 10 × 10 cm2. The full cell configuration consisted of a NiO+8YSZ anode supported layer / NiO+8YSZ anode layer / ScSZ electrolyte layer / 10GDC cathode barrier layer / LSC cathode layer. Electrical properties of these cells were tested by adjusting the production parameters such as green sheet thickness, sintering temperature, etc.
Large-size planar anode-supported SOFC cells were prepared using a wet ceramic process. Production equipment including doctor blade casting machines and screen printing machines were mainly employed to ensure that the cells are manufacturability. The anode half-cell substrate was produced by laminating green casted sheets and co-firing. The flatness and strength of the substrate were evaluated using optical non-contact planar measuring instrument and mechanical universal testing machine. The results revealed that the different shrinkage of each green sheet layer during sintering led to substrate warping, and the warping attributed to constraint sintering effect. The warp level could be adjusted by varying the thickness of the anode support layer. On the other hand, three-point bending test of half-cell substrates with different thicknesses is roughly the same, but the maximum pressure tolerance increases as the thickness increases.
The cathode barrier layer (10GDC) and cathode layer (LSC) were produced and sintered layer by layer on the anode half-cell substrate using a screen printing process. The full cell was encapsulated and its electrochemical behavior was evaluated by conducting measurements using an electrochemical analyzer. Hydrogen gas was supplied at the anode side while air was supplied at the cathode side, with the operating temperature range set between 650°C and 750°C. The effects of differences in gas flow, operating temperatures, anode supported layer thickness, and different half-cell sintering temperatures on electrochemical properties were investigated. The results revealed that as the gas flow rate and the operating temperature increase, the current density and electrical power density both show an upward trend; as the thickness of the anode-supported layer decreases and the sintering temperature of the half-cell increases, the electrical properties reach the highest level, and the current can reach the maximum after running at 750°C for 8 hours up to 103.27 A, with a maximum electrical power density of 892.70 mW/cm2. The experimental results demonstrated that SOFC cells prepared with mass production equipment and techniques, in addition to mass production and good sintering yield, can also have good electrical performance under medium-temperature operating conditions.
