Abstract

Mechanical failure and performance degradation found in solid oxide fuel cell (SOFC) are often related to higher thermal stress generated in operating procedures. In this chapter, various numerical studies in this topic are summarized and outlined in terms of modeling and simulation methods. As a case study, a multiphysical coupled model is applied and presented aiming to explore and analyze the thermal stress distribution and the stack operating parameters effects (e.g., the gas composition, current, and temperature distribution). The effects of the stack design parameters are also investigated for different flow channels (i.e., coflow and counter-flow), electrolyte layer thickness, manifold position, etc. This chapter provides a valuable reference in evaluating the thermal behavior and effects on the electrochemical cells/stacks.
