本研究是以美國阿崗國家實驗室(ANL)所發展之GCTool為模擬工具，針對固態氧化物燃料電池(SOFC)結合燃氣渦輪機(GT)複合系統，並且在系統建構二氧化碳再處理器，進行數值模擬分析。而二氧化碳重組器在此系統設計中，為主要重點之ㄧ，至今尚無有相關文獻將二氧化碳重組反應運用在SOFC系統設計；在本系統設計當中，將會建構二氧化碳重組器於SOFC陽極出口處，以達到二氧化碳重組再利用效果；但是模擬結果顯示，因為轉化反應和重組反應伴隨發生，以及燃燒室燃燒反應，以致於無法減少氣體中二氧化碳之比例，卻能增加系統效率約7.5%左右。本研究另外設計一組雙SOFC結合燃氣渦輪機與二氧化碳重組器之系統，供給相同系統燃料熱值以及排放相同二氧化碳量之前提下，可以產生更多的能量。在成本方面，使用雙SOFC系統雖然貴一點，但是性能方面卻較優越。

The simulation model GCtool (general computational toolkit) developed by ANL has been employed in the simulation analyses of a SOFC/GT hybrid electricity generation system combined with a carbon dioxide recovering system. A carbon dioxide reformer has also been installed at the outlet of the anode of the SOFC, in hope of recovering the carbon dioxide of exhaust gases. However, due to the occurrence of the water-gas shift reaction in the reforming reaction, the content of the carbon does not reduce as expected, but the efficiency of the system does improve by 7.5 %. Another system that employes dual-SOFC’s combined with a GT and a CO2 reformer is proposed. The result obtained from the present analysis show that with the same emission of CO2, the new dual-SOFC system design generates more power output, although the cost is higher.
