摘要:	?用油壓壓片與700°C 燒結製備氟化鑭電解質片，再?用濺鍍技術製備白?/氟化鑭/白?電極，進?氟化鑭之電化學性質分析。?用循環伏安與極化曲線之分析結果發現，白?/氟化鑭/白?電極經90°C 水蒸氣之前處?後，確實可提升電極上之電化學反應速?（電?），且在?續30次以上之循環伏安實驗後，其電解質電阻提高，限制?電?之輸出，其原因推測為在循環伏安實驗中隨著掃描次?的增加，其水分含?減少所致。因此水分於氟化鑭電解質內部扮演很重要的?子導電角色。 Pt/LaF3/Pt was prepared by sputtering Pt on the disk-typed LaF3 electrolyte that was prepared by pressing the LaF3 powder and sintering at 700?C. The electrochemical characteristics of the LaF3 plate were analyzed in this study. The experimental results of cyclic voltammetry (CV) and polarization curve in the presence of N2 with 100% R.H. indicated that the electrochemical reaction rate (current) was significantly improved when Pt/LaF3/Pt was pretreated in 90?C aqueous vapor. When the cycle number of CV was greater than 30, the current was limited by the increased resistance of LaF3. The increase in resistance was considered to be the result of humidity loss within LaF3 as the cycle number of CV increased. Therefore, the conductivity of LaF3 was significantly affected by the humidity in the structure of LaF3.
