固態氧化物燃料電池(SOFC)已被開發為能量產生的裝置，具有約60%的高能量轉換效率和燃料選擇的靈活性，本篇研究為整合SOFC上下游製程設計，需建立完整的50KW系統製程，透過商用軟體Aspen Plus® 於Aspen Custom Modeler (ACM) 建立動態響應SOFC電池堆數學模型，調整參數使模型與設備擬合並用於動態及穩態模擬操作，另外，可延伸應用於Aspen Plus® 進行製程評估使用。本研究初期先與1KW SOFC的工廠數據進行數學模型的驗證，在建立數學模型的過程中發現，若此數學模型與過去文獻中只考慮氫氣的電化學模型所得到的模擬結果將與工廠數據有明顯的差異，故本研究引用一氧化碳的電化學模型，並調整電池規格及材料性質，完成小規模SOFC數學模型的驗證。從模擬結果來看，當考慮兩種電化學反應時，模擬和實驗結果的誤差相較於只考慮一種電化學反應明顯下降。完成SOFC數學模型的建立後，再透過Aspen Plus建立50KW SOFC完整的製程系統，與工廠數據進行數據驗證，並完成動態及穩態操作的模擬。

Solid oxide fuel cells (SOFCs) have been developed as energy generating devices with around 60% high energy conversion efficiency and great flexibility in fuel selection. In this study, the SOFC related operations and process design technologies are required to integrate up and down streams of the SOFC system. Hence, the purpose of this study is to establish a dynamic response SOFC mathematical model in Aspen Custom Modeler (ACM) through Aspen Plus®, and adjust parameters to fit models and unit operations for dynamic and steady-state simulation operations, and extend to Aspen Plus® for process evaluation. At the beginning of the study, the model was verified with the factory data of 1KW SOFC. In the process of establishing the model, it was found that if the model only considers the electrochemical model of hydrogen, which is same as the past literature, the simulation results were significantly different from the factory data. Therefore, this study cites the electrochemical of carbon monoxide and adjusts the fuel cell specifications and material properties to complete the verification of the small-scale SOFC model. From the simulation results, when considering two kinds of electrochemical reactions, the error between the simulation and experimental results is significantly lower than that of considering only one electrochemical reaction. After establishing the SOFC model, a complete 50KW SOFC process system was established through Aspen Plus in order to verify the factory data, and the dynamic and steady-state operation simulation has been completed.
