Abstract
A novel temperature control system (TCS) integrated solid oxide fuel cell (SOFC) stack is designed to address the thermal management challenges in SOFC stacks. The investigation includes identifying potential temperature control fluids (TCFs) for the TCS with numerical testing conducted on two specific TCFs, steam and FLiNaK. Utilizing advanced CFD modelling and FEA techniques, a fluid cooled SOFC stack was meticulously designed and evaluated to correlate TCF properties with stack’s electrical and thermal performance. The results demonstrate the TCS’s effectiveness in managing thermal issues with potential to optimize stack performance by controlling the TCF’s inlet temperature. Overall, this research emphasizes the transformative potential of TCS-integrated SOFC stacks in achieving thermal regulation and sustainable energy generation.Description
