Abstract
Solid oxide fuel cells (SOFCs) are being recognized as one of the promising energy conversion technologies. To study SOFCs systems operation, numerical modeling is a helpful tool, which allows one to understand and improve their operation. Moreover, a crucial feature of numerical modeling is the opportunity to reduce economical and time cost in prototyping methodology. In this work, a banded SOFC stack, which includes six 12 mm x 12 mm cells, connected in series, applied on a single electrolyte support, is studied numerically, using the finite-volume method. A mathematical model, which includes the heat, mass and electron/ion transport phenomena, was provided. To validate the model, a comparison of electrical characteristics obtained from the numerical and experimental study was performed. To inspect the possibilities of applying geometrical improvements to the existing prototype design, different versions of fuel and air channels were numerically modeled and inspected, including the option of extending the system into two or more stacks, connected by a shared fuel channel of two adjacent stacks. Moreover, the influence of the electrolyte thickness was tested. The proposed design modifications enhance the system by reducing the volume of the stack and improving the electric performance compared to the existing prototype design. The numerical model can be used to test further design modifications to the stack, including performance analysis by changing the operating parameters of the system and applying new materials.
