<p>This study examines the Multiphysics modeling and simulation of solid oxide fuel cells (SOFCs) to optimize thermal, electrical, mechanical, and electrochemical performance. By integrating key physical phenomena, the coupled model highlights significant interactions, improving predictions of temperature, electrical potential, and stress distributions compared to non-coupled models. The simulation results demonstrate that temperature distribution is significantly influenced by ohmic losses and electrochemical reactions, with coupled models predicting more realistic thermal gradients. Electrical potential varies with temperature and material properties, with coupled models showing a more gradual potential distribution. Mechanical stress simulations reveal maximum stress in high thermal gradient areas, which are underestimated by non-coupled models. These findings emphasize the importance of Multiphysics approaches for efficient and durable SOFC designs, with potential applications in clean energy production and renewable fuel integration<b>.</b></p>
