An Energy Integrated Solid Oxide Fuel Cell System: Modeling and Simulation

Abstract:

As a solid oxide fuel cell (SOFC) system is under dynamic development for a profitable use in the future, it is very important to understand its transient characteristics. In this paper, the modeling and simulation of an energy integrated SOFC system has been performed to analyze the dynamic characteristics of the heat integration. The lumped models of the energy integrated SOFC system are developed and simulated to present the results of open loop response of the temperatures of SOFC, steam reformer and air inlet stream. The simulation results showed that the air flowrate has a dominant effect on the temperature of SOFC while the valve position and the heater power supply noticeably affect the reformer temperature and air inlet temperature, respectively. Therefore, the match of major influence of input step change on the temperatures of SOFC, steam reformer and air inlet stream in the energy integrated system is very practical for an effective control strategy in the development of control system design.
