Modeling And Simulation Of Solid Oxide Fuel Cell System

Abstract

With the increase in the rate of depletion of conventional energy sources, the increased volatility of fossil fuel prices and the environmental externalities of fossil fuels, particularly greenhouse gas (GHG) emissions the world has shifted its focus on renewable energy sources. This paper focuses on the study of fuel cells as a renewable source of energy which is environment friendly and much more consistent in performance as compared to solar and wind energy. This paper deals with the study of dynamic model of solid oxide fuel cell (SOFC) based on transfer function. The studied model includes the effect of activation, ohmic and concentration losses on the dynamic performances of SOFC. The performance of the model is tested for constant utilization mode and constant fuel flow mode of operations. The effect of varying operating temperature on the performance of SOFC is also analyzed for two modes of operation in the present work.
