近年來，由於人們不斷使用化石燃料造成溫室效應，導致氣候變遷。為了減少二氧化碳的排放問題，本研究透過固態氧化物燃料電池(SOFC)/氣渦輪機(GT)/蒸汽渦輪機(ST)結合具鈣迴路碳捕捉功能的產氫系統，設計出同時滿足低二氧化碳排放量兼具高效率之獨立式混合發電系統。
首先使用Aspen Plus 軟體模擬具碳補捉的產氫系統，結合蒸氣重組與鈣迴路生產氫氣，並透過優化及熱整合之設計，找到最佳的操作條件。接著透過了獨立式的設計後，產氫系統不需外界熱源，更完整考量系統與二氧化碳的排放關係。
最後，透過MATLAB/Simulink軟體建立固態氧化物燃料電池模型，結合獨立式產氫系統、氣渦輪機及蒸汽渦輪機等程序，將燃料電池出口之高溫廢熱回收進行發電，成功設計出低碳排的獨立式混合發電系統。同時提供另一種低碳排的獨立式混合發電系統之設計，將鈣迴路探捕捉程序用於捕捉燃料電池出口廢氣之二氧化碳，並探討此兩種設計對於發電效率及二氧化碳排放量的影響。所建立之混合發電系統之熱效率最高可達84.86%。

This research provided a stand-alone, low carbon-emission and high efficiency hybrid power generation system which combines SOFC/GT/ST with a hydrogen production process based on the calcium looping process. The hydrogen production process which combines steam reforming process with calcium looping process is built in the Aspen Plus. By using Optimization and heat recovery, the process has been improved but still needs external heat resource. Therefore, this paper provide a stand-alone process design which can consider CO2 source in the production process more completely. Finally, this research using MATLAB/Simulink to build SOFC stack and successfully design a stand-alone and low CO2 emission hybrid power generation system which combined SOFC with GT and ST to recovery the heat of the flue gas from the afterburner. Additionally, this research provides another design of low CO2-emission of the hybrid power generation system which can capture CO2 in the outlet of the fuel cell through the calcium looping process. We also discuss the influence on electric efficiency and CO2 emission between these two different designs. The hybrid power generation system performed a high efficiency up to 84.86%
