固態氧化物燃料電池系統必須在高溫下運作，從室溫升溫至工作溫度的起機程序是一個重要的課題。此起機系統包含了燃料電池堆、尾氣續燃器、質量流率控制器、分/合流閥以及熱交換器等，藉由正確的起機策略可避免因為過高的溫度梯度產生元件的損壞。
本論文旨在發展起機策略，使燃料電池在起機模式時，藉由控制進入電池堆的空氣和燃料的質量流率和溫度，使電池堆的溫升率維持在可接受的範圍之內以縮短起機時間，利用模糊滑動控制設計溫升率控制器及進氣溫度控制器。本文利用一個包含質傳模組、熱傳模組以及電化學模組的平版型電池堆之動態模型，進行起機模式的動態模擬，以Matlab/Simulink執行電腦模擬，其模擬結果可描述固態氧化物燃料電池起機時之動態響應，並提出固定入口溫差值 及變動入口溫差值 之兩種架構，模擬結果顯示變動 比固定 值有較短之起機時間。本文所建立之固態氧化物燃料電池動態模擬程式，可在設計階段分析燃料電池之動態特性，並分析起機模式策略，以得到最短之起機時間。

Solid oxide fuel cell (SOFC) has to be operated in high temperature. The start-up strategy for heating up the cell from room temperature to operating temperature (800℃) becomes an important issue. The SOFC system includes a solid oxide fuel cell stack, an off-gas burner, mass flow controllers, flow divider/combine valves and heat exchangers. The temperature rising rate in the start-up process has to be controlled to avoid components’ damage due to too large temperature rising rate.
This thesis aims to develop the start-up strategy combining the temperature rising rate control and the inlet temperature control. The controllers are designed by using the fuzzy-sliding mode control theory. The planar SOFC dynamic model which includes mass transfer module, heat transfer module and electrochemical module to simulate the start-up process.
Computer dynamic simulations are performed by Matlab/Simulink to analyze the dynamic response of the SOFC stacks during start-up mode. This paper proposes the fixed inlet temperature and the variable inlet temperature concepts. The simulation results show that variable inlet temperature can have shorter start-up time than the fixed inlet temperature. The developed dynamic simulation program can be used to analyze the start-up mode and design the suitable start–up strategy
