本論文利用厚膜技術的刮刀成型手法製作電解質(Electrolyte)和陽極(Anode)，並使用網印的方式製作電極(Electrode)，將電極網印在單獨燒結與電解質和陽極共燒之後的電解質表面。而電解質改質則藉由YSB( 75mol%Bi2O3 + 25mol%Y2O3 )的微量添加，使 (ZrO2)0.92 (Y2O3)0.075 (MgO)0.005 ( YSZM )材料系統之燒結溫度下降，改善與電極共燒溫度限制。
由實驗結果可以發現，漿料之溶劑為異丙醇、正丁醇、甲醇混合溶劑時，固定固含量的條件下，黏度將會隨著溶劑的增加而下降；電解質及陽極漿料利用此混合溶劑系統，皆可刮出良好的薄帶，其漿料黏度皆在1100cp，而漿料呈現所需的假塑性流體型態。為了得到更好的薄帶，由黏結劑與分散劑技術資料可知選用適合的溶劑，分別為丁酮與乙醇，經過實驗可以清楚的知道溶劑改為丁酮與乙醇之混合溶劑之配方，可以得到更良好的薄帶，黏度隨著溶劑的添加而降低，而在1500℃ 3 小時的燒結條件下，其相對密度為98.93%。經過燒結過後可以發現，陽極和電解質共燒之試片，雖然利用掃描三次元量床量測後，平整度誤差Error of Uniformity約為26%，不及電解質單獨燒結之試片來的平整（Error of Uniformity約為21%），而且電解質的緻密性也會受限於陽極的燒結溫度，而無法得到緻密的電解質，因此最後改用電解質單獨燒的方式，得到緻密的電解質後再將陽極和陰極，分別網印在電解質上，並分別燒結電極，最後即可得到所需的單電池。
YSZM電解質藉由YSB的微量添加改善燒結溫度，經由實驗結果可以知道，當3mol%的YSB添加至YSZM (3YBZM)時可以得到穩定的C相，而燒結溫度在1200℃持溫5小時可以得到緻密的試片，其相對密度為95%，而在800℃的導電率為0.0204 S/cm，相當於YSZM在800℃的導電率0.022 S/cm。
因此由上述結果可知8YSZ及YSZM若要得到緻密性95%以上之試片，其燒結溫度都必須在1500℃，而在800℃的導電率分別為0.015 S/cm、0.022 S/cm，3YBZM在1200℃的燒結條件下可以到相對密度為95%之試片，而在800℃的導電率為0.0204 S/cm，因此可知3YBZM將有利於與電極共燒。

Electrolyte and anode thick films were successfully fabricated using tape casting technique and co-firing of electrolyte and anode was implemented by screen printing the anode on electrolyte. In addition, low processing temperature electrolyte made of (ZrO2)0.92(Y2O3)0.075(MgO)0.005 (YSZM) and YSB(75mol%Bi2O3+25mol%Y2O3) is developed in order to co-fire significantly with electrodes.
Viscosity of the slurry prepared for tape casting was found to decrease with increase of solvent content mixed with isopropyl alcohol, butyl alcohol and methyl alcohol. Better quality tape is achieved with the slurry prepared by mixing appropriate amount of solvent and the slurry become pseudo-plastic fluid type when the viscosity of the slurry is about 1100cP. The relative density of the tape sintered at 1500oC for 3 h is 98.93% of theoretical density. The error in uniformity is about 26%, when the anode is co-fired with electrolyte and the error in uniformity of the electrolyte is lowered when it is sintered separately. Since, in the co-firing process, the sintering temperature of the electrolyte depends on anode, hence the densification of the electrolyte is poor. Therefore, in the present study electrolyte is sintered first for better densification and electrodes are sintered after they are screen printed on the surface of electrolyte to fabricate a single cell.
In addition, low sintering temperature electrolyte of YSZM is developed by adding small amount of YSB. Stabilized cubic phase is observed when the content of YSB is 3mol%, indicating that the minimum content of 3 mol% YSB should be added to pure YSZM electrolyte to stabilized it in cubic phase. All the compositions are sintered at 1200oC for 5hr to achieve densities of about 95% of theoretical density. The ionic conductivity of 3mol%25YSB added YSZM electrolyte is 0.0204 S/cm at 800oC, which is near to the conductivity of pure 8YSZM at the same temperature.
8YSZ and YSZM electrolytes were found to require the sintering temperature of 1500oC to achieve densities of about 95%. Hence, it can be concluded that the new electrolyte developed by adding 3mol%25YSB to pure YSZM sintered at 1200oC with density of 95% and ionic conductivity of 0.0204S/cm can be replaced for 8YSZ electrolyte for intermediated temperature solid oxide fuel cell application. It is also concluded that this electrolyte is suitable to co-fire with electrode by saving time and energy.
