This paper presents a comprehensive mathematical model and simulation of Solid Oxide Fuel Cell (SOFC) in a single cell model. Steady-state responses of SOFC are analyzed based on operating condition points for each operating mode i.e. constant fuel flow (CFF) and constant fuel utilization (CFU). For the CFF mode, the six operating conditions are fuel flow, air flow, fuel utilization, pressure, fuel temperature and air temperature, whereas, in CFU, the operating conditions are fuel utilization, air to fuel ratio, and current limiter, pressure, fuel temperature and air temperature. These changed operating points are directly analyzed for changes in the output voltage, power, electrical efficiency, temperature, heat power and heat efficiency of a single tubular SOFC. From the analysis, it is observed that those six parameters have a significant impact on the generation of maximum power and efficiency for electricity and heat generations. The proposed model can be used to find the optimal parameters of SOFC that will produce the maximum electrical and heat power as well as their efficiencies. It also can be extended into the stack model for larger systems.
