本論文研究以鑭鏑鉬鎢氧化物(La2-xDyx)(Mo2-yWy)O9電解質為主，燒製電解質支撐單電池和陽極支撐單電池，再分別以單氣室測試系統和雙氣室測試系統進行功率量測。 藉著XRD繞射圖譜去確認電極及電解質的製作是否煅燒成單一純相，並改善製程方法。 藉由微觀電子顯微鏡使用，來觀察單電池個別的微結構，分析加以改善。
電解質支撐單電池搭配不同陽極材料進行功率密度量測，此電池為 (La0.6Sr0.4)(Co0.8Fe0.2)O3-δ / Ce0.9Gd0.1O2 / (La2-xDyx)(Mo2-yWy)O9 / Anode，在7500C時，陽極 (La2-xDyx)(Mo2-yWy)O9+NiO(1:1) 的功率表現優於其它電極材料，其功率密度為 67.1 mW/cm2。 接著分別改變測試溫度電解質厚度。溫度7500C時，觀察出得到電解質厚度減少至0.4mm時 ，其功率密度反而是下降的，此時功率只有50.8 mW/cm2，比電解質厚度0.7mm時的67.1 mW/cm2功率低，很明顯地，試片發生漏氣問題。但普遍來說，功率密度跟文獻的數值相比還是小了許多，歸咎於下列幾種原因，電解質膨脹係數過大，強度過低，在密封匹配難找到氣封玻璃材質，因為在升溫過程中，試片跟跟氧化鋁管膨脹係數差異過大，產生熱應力，且試片強度過低，導致試片承受不住，試片裂開，所以我們最佳的封法使用二層氣封膠，但此方法漏氣情形仍相當嚴重，也因此我們的功率密度一直無法提升。
陽極支撐單電池則是以單氣室進行測試功率密度，此單電池為(Ba0.5Sr0.5)(CoxFe1-x)O3-δ/Ce0.9Gd0.1O2/(La2-xDyx)(Mo2-yWy)O9/ Ce0.9Gd0.1O2+NiO。 在6000C時，功率密度可達到157.9 mW/cm2。單電池的效能最佳，陽極支撐單電池單氣室的OCV值比電解質支撐單電池還低，但電流密度卻大了許多，因為陽極支撐單電池的電解質厚度只有40µm比電解質支撐單電池 700 µm 小了許多，所以歐姆電阻相對地比較小，不需要氣封的單氣室量測結果明顯較雙氣室結果為佳。

In this work, we study the LDMW-based solid oxide fuel single cells with the electrolyte-supported and anode-supported configurations electrolyte. The power density was measured, using single-chamber or two-chamber cell testing system. The texture structure and morphology were investigated by X-ray diffraction and scanning electron microscopy. The XRD results indicated that the structure of electrodes and electrolyte were single phase.
The single cell coated the different anode material for electrode-supported was measured in two-chamber cell testing system at 7500C. The results indicated that the power of single cell with (La2-xDyx)(Mo2-yWy)O9 NiO(1:1) anode was higher than the others and its power density was 67.1 mW/cm2. In optimize conditions of different temperature and electrolyte thickness, the power density of single cell with the electrolyte thickness(0.7mm) was the highest at 7500C. Decreasing the electrolyte thickness to 0.4mm, the power was only 50.8 mW/cm2. Obviously, The electrolyte was cracked. Since the power density was much lower than the data in the literature. Two plausible causes are the TEC value of LDMW is too high and its strength too weak. The TEC of LDMW is much higher than the that of the Al2O3 tube, the thermal stress was demonstrated too much for LDMW. Thus we sealed the single cell with two types of paste on two-level way. Still, the result of sealing was not very good. The appearance of the crack lines was very obvious.
The single cell for anode-supported (Ba0.5Sr0.5)(CoxFe1-x)O3-δ / Ce0.9Gd0.1O2 / (La2-xDyx)(Mo2-yWy)O9 / Ce0.9Gd0.1O2+NiO was measured in a single-chamber cell testing system and the maximum power density was 157.9 mW/cm2 at 6000C. the performance of single cell was higher. The OCV of the single cell for anode-supported was lower than the single cell for electrolyte-supported. It may result from the electrolyte thickness was lower than the single cell, the value of the ohm resistance decreased. The result of power density measured in the single-chamber testing system was much better than the two-chamber testing system.
