This comprehensive study explores groundbreaking innovations in the realm of solid oxide FCs (SOFCs) with a particular emphasis on fuel cell (FC) modeling, parametric analysis, and performance evaluation. The research delves into the intricate dynamics of a hydrogen-powered tubular SOFC, dissecting various parameters that influence its operation and efficiency. Innovation lies in the meticulous examination of how temperature, FC operating pressure, air flow rate to fuel input ratio, and wider gas channels impact FC efficiency and power production. The study employs a distinctive electrochemical approach to scrutinize pile factors and their effects on efficiency, shedding light on the interplay of fuel efficiency factor, current density, and actual voltage. Notably, the study introduces a novel approach by setting the current density to 7030 A/m2 and the efficiency factor to 0.7, leading to a substantial enhancement in FC efficiency and power output. Furthermore, the research delves into the optimization, electrochemistry, and thermal dynamics of SOFCs, conducting a thorough comparison of current findings with reliable sources to ensure accuracy and reliability. Results indicate a substantial improvement in fuel efficiency, current density, and actual voltage, resulting in increased FC efficiency and power output. The study observes a consistent decrease in fuel usage across various scenarios. Additionally, the research dispels concerns about the impact of lowering inlet temperature on channel temperature disparity, providing valuable insights for the advancement of SOFC technology.
