Abstract

This study investigates the impact of temperature variations on the performance of Solid Oxide Fuel Cells (SOFCs), a high-efficiency energy conversion technology. The research aims to simulate the performance of SOFCs across different operating temperatures, characterize the resulting current and power densities, and validate the model with experimental data. The methodology uses COMSOL Multiphysics to simulate electrochemical and thermal behaviours. Data analysis evaluates trends in performance metrics and assesses the impact of temperature variations on efficiency and stability. The findings show that elevated temperatures improve electrochemical activity and power output, with an optimal balance at intermediate temperatures. Excessive temperatures result in material degradation and diminished system durability. The study provides insights into optimizing SOFC performance through effective temperature management, material selection, and structural design enhancements. Future research will focus on refining the simulation model and investigating innovative materials to improve SOFC efficiency and longevity, advancing sustainable energy solutions.
