Abstract:
This study establishes a system loop analysis model for SOFC systems incorporating thermal components through thermodynamic theory. The model can be used to evaluate the overall efficiency, power generation, and operating status of components in SOFC systems under different operating conditions. Additionally, using a commercial stack module, the study completes the analysis of afterburner temperature and the effects of using SR and ATR reformers on the temperature, power generation, and efficiency of the SOFC system. The optimal system performance was found to be a power generation of 7.62 kW, an efficiency of 64.3%, and a stack temperature of up to 803℃. Finally, system analysis reveals that using an ATR reformer effectively reduces the combustor temperature and indicates room for optimization of the steam-to-carbon ratio when using an ATR reformer. This result can guide future experiments for optimizing SOFC system design and parameter control.
