摘要

固態氧化物燃料電池(SOFC)是屬於操作在高溫中的燃料電池，所
以電池本體材料需使用耐高溫之材料，各零件也需要耐高溫，在實驗之前，需要之活化過程為NiO 的還元反應，目的在於將NiO 還原成可以導電的Ni，但文獻中對於SOFC 的活化條件探討極少，本實驗
主要研究各種不同之活化方式，探討以陽極端為支撐結構之SOFC，
其陽極端主要是由NiO（導電物質）和YSZ（電解質）所組成，需將
NiO 還原成金屬Ni，以提高其導電度以及反應速率，而活化之目的
在於將NiO 還原成可以導電的Ni，傳統活化方式為在陽極端通入氫
氣，讓氫氣在高溫中對NiO 進行還原，在本實驗中使用了兩種新的
活化方式，閉路方式活化，以及掉換燃料方式活化兩種活化方式，改
變陽極端中之反應方式，可提高在短時間內之活化效率和長時間之活
化完整性，藉此加速反應啟動時間與反應效率。
第二個實驗為研究自製之膜電極組，本實驗主要是自行壓合燒結
膜電極組，測試自行製作之膜電極組之性能，實驗中使用商購之薄片
狀材料，並以對稱方式堆疊燒結，找出最佳之製作參數，並量測其性

The solid oxide fuel cell（SOFC） is the fuel cell operating at the
high temperature. The identity of the fuel cell has to use the materials
which can operate in high temperature. Before the experiment, the
activation is the reduction reaction of the NiO in order to reduce the NiO
to Ni which have better conductive. The study in this experiment
researches on the different activation methods. The main materials of the
anode side are NiO and YSZ. The NiO is not a good electric conductor.
Before the experiment is the reduction the NiO return to Ni, and the Ni is
a good electric conductor. We used the different activation conditions to
observe the different between the performance and the activation
conditions. The main different is the movement of the O2- ion. The
traditional activation conditions only reaction on surface. The new
method one is to close the electric cycle and the other one is to change the
fuel from anode side to cathode side reaction at the deep place close to
the electrolyte. The activation condition of the short circuit had the
overall reaction.
The second experiment researches the SOFC producing by self and
experiment the performance with the SOFC. In this experiment operated
with the commercial materials. And find out the best sintering conditions
with the regular stack method.
