本研究主要評估基於固態氧化物燃料電池(SOFC)及固態氧化物電解電池(SOEC)與再生能源結合之系統性能。此系統利用SOEC將再生能源多餘之電力產生氨氣，再由SOFC通過裂解氨氣後進行發電，其中系統採雙邊同時運行，加入不同組件維持系統運作如:熱交換器、後燃室、電熱器維持電堆運作並提升系統效率，並且評估不同裂解比例、溫度、燃料利用率、蒸氣利用率及熱損對於子系統的影響。此外，本研究也對兩種不同產氨氣之方式進行評估，觀察不同產氨氣方式對於系統效率的影響。
為了評估上述不同參數對於系統的影響，本研究建立了數學模型，模擬整個系統運作過程中不同參數對於系統的響應，其中為要探討能量轉換之問題，而熱力學法唯一探討能量轉換之科學，因此本研究採用熱力學法進行評估。而從結果可以得知，對於使用氨氣料源的SOFC電堆而言，溫度每上升50K電堆最大輸出功率可以上升10.4%。對於SOEC電堆而言，溫度每上升50K產氨效率平均上升2%。不過隨著溫度升高也要考慮熱損組件的問題，可以看到熱損從1%上升至10%時對於電熱器所需的功率增加了0.67KW上升了30% 。
本研究模擬氫氣及氨氣流量計算了不同氨氣裂解比例的結果，以SOFC而言以873K的溫度為例，最大輸出淨功在裂解比例為80%為24.1KW，然而在90%時的最大輸出淨功為24.16KW，而在溫度1073K燃料利用率為90%時有最大的系統效率；而對於SOEC而言，在溫度1073K蒸氣利用率為70%時有最大的產氨氣效率。
而比較不同SOEC的產氨氣子系統，使用SOEC-HB產氨對於產氨氣的效率是有提升的，在四個溫度哈伯法產氨氣平均比直接氨氣還多9%的功率輸入，因此對於使用哈伯法產氨之子系統是可行的。
透過完成此研究可以根據不同熱損模擬出來的結果進行設計。再來透過模擬不同裂解比例結果，可以看出對於系統的影響，也能夠對於不同電解質材料有不同裂解比例能夠有一定的參考價值。

To evaluate the effects of these different parameters on the system, a mathematical model was established, and thermodynamic analysis was used to simulate the system's response to different parameters. The results show that for the SOFC stack using ammonia as fuel, the maximum output power increases by 10.4% for every 50K rise in temperature. For the SOEC stack, the ammonia production efficiency increases by an average of 2% for every 50K rise in temperature. However, as the temperature increases, the issue of heat loss must be considered. It is observed that when heat loss increases from 1% to 10%, the power required by the electric heater increases by 0.67kw, a 30% rise.
This study simulates hydrogen and ammonia flow to calculate the results of different ammonia decomposition ratios. For SOFC, at a temperature of 873K, the maximum net output power is 24.1KW at an 80% decomposition ratio, while the maximum net output power is 24.16KW at a 90% decomposition ratio. At a temperature of 1073K and a fuel utilization rate of 90%, the system efficiency is maximized. For SOEC, at a temperature of 1073K and a steam utilization rate of 70%, the ammonia production efficiency is maximized.
Comparing different SOEC ammonia production subsystems, using the SOEC-HB for ammonia production improves ammonia production efficiency. At four temperatures, the Haber process produces an average of 9% more power input for ammonia production than direct ammonia, making the Haber process a feasible subsystem for ammonia production.
