可逆式固態氧化物燃料電池(Unitized Regenerative Solid Oxide Fuel Cell, URSOFC)是將固態氧化物電池的發電模式SOFC(Solid Oxide Fuel Cell, SOFC)與電解模式SOEC(Solid Oxide Electrolyzer Cell, SOEC)相結合，用以來達到在同一系統中可以分別進行電池模式放電與電解模式儲能兩種功能。SOFC可以在用電尖峰時刻進行發電提供電力，而SOEC可以於離峰時刻進行逆反應來產氫儲能；而氫氣在工業領域是相當有用的氣體，除了可提供工業應用之外，亦為燃料電池發電時所不可或缺的重要燃料之一。本研究致力於固態氧化物燃料電池燒結製備流程之精進，使燒結製備完成的固態氧化物燃料電池元件達至理想之平整度及變形量，藉此以降低電池組裝時的困難及增加美觀；本實驗嘗試改變了過往舊製程燒結前的電池膜材裁切工具以及邊長裁切量為71mm後得出了最佳變形量。此外也對電池燒結的升溫時間進行了縮短調整，藉此改變了升溫速率使得電池晶粒結構改變並於實驗測試中得出提升了三倍多的性能表現。另外於目前所使用的電池夾具外自製設計出了可以外接的燃料氣體預熱器，並且利用了此裝置提升了將近兩倍的電池放電性能與三倍多的電池電解性能。

Unitized Regenerative Solid Oxide Fuel Cells (URSOFCs) combine solid oxide fuel cell (SOFC) and solid oxide electrolyzer cell (SOEC) functionalities in order to create a system which can discharges electricity and store energy. When in the peak electric load, SOFCs can generate electricity and supply electric power; while, in the off-peak electric load, SOECs can store hydrogen in hydrogen storage tanks. Hydrogen is one of the most useful gas in industrial as industrial applications. Despite hydrogen’s widely used applications in industrial gas, hydrogen is one of a necessity for fuel cell based power generation stations. This study investigates the Solid Oxide Fuel Cell sintering preparations and processes’ improvement. By investigating in sintering preparations and processes, the ideal Solid Oxide Fuel Cell flatness and deformation can be achieved to reduce the difficulties in cell assemblies and increase cell aesthetics. This study tries to change the cell membranes of the anode cutting tools and side length before sintering it and get the optimum deformation when the length is 71mm. In addition, the cell heating sintering time was shortened to increase the heating rate. After changing the heating rate, it making the cell grain structure also changed. The heating rate will affect the porosity of the anode structure. And in the experiment test result shows that it improves the performance of the Solid Oxide Fuel Cell about three times. This study also designed and manufactured a fuel gas preheater that can be connect to the current button cell fixture. And use the fuel gas preheater it can improve the performance twice in SOFC mode and three times in SOEC mode.
