摘要
相較於其他類型燃料電池，固態氧化物燃料電池是可於高溫操作，具有高性能與利用多種類型燃料之優點。本研究採用陽極支撐之膜電極组，於實驗前需經過一活化前處理過程才可進行反應，目的在於將陽極之氧化鎳還原成金屬態，除了可導電外更可與氧化鋯結合成三相面以作為反應區。傳統前處理方式為在陽極端通入氫氣，讓氫氣在高溫長時間過程中將氧化鎳進行還原。除傳統方法外，本研究於前處理過程中通入電流，旨在探討其於活化過程對電池性能與陽極微結構之影響。藉由不同前處理方法之實施，閉路操作將能加速陽極之活化效率。透過微結構、導電度、與元素分析，電流穿透被證實能有效增加陽極微結構之三相位以於短時間內完成前處理過程。最後，本研究以提出電流穿透與否對陽極微結構中氧化鎳還原至金屬態之反應機制作為總結。

Comparing with other types of fuel cell, advantages of solid oxide fuel cell (SOFC) include high temperature operation, high efficiency and tolerance of all kinds of fuel. In this study, anode supported membrane electrode assembly (MEA) is adopted. Before cell operation, pretreatment on anode is needed for the reduction of NiO to Ni. Traditional pretreatment process exposes NiO to hydrogen environment at high temperature with long period of time. In addition to traditional process, this study emphasizes on the effects of closed circuit operation on anode microstructure and cell performance. By carrying out the methods, the pretreatment using current pass-through is found to be effectively and efficiently. Accompanying with SEM, conductivity and element analysis, increase of three phase boundary is considered to give rise to changes in the anode microstructure, leading to activation of the anode. Mechanisms of NiO in anode reducing to Ni and porous structure via different pretreatments and their effects on the anode microstructure are proposed.
