摘要：
In the past decade, developing solid oxide fuel cell (SOFC) systems for micro combined heat and power applications (micro-CHIP, 1-10 kW(e)) is one of the hot spots in the world energy field. To meet the requirements for system optimization and control design of SOFC micro-CHIP systems, in this paper a dynamic model of an SOFC micro-CHIP system is developed, based on which dynamic simulations are also carried out. Simulation results show that the present model can reflect the behavior of the SOFC micro-CUP system quite well; the influence of one component on another is an important factor to determine system dynamic behavior; as the system comprises many components and concerns different physical and chemical processes, it has dynamic processes with several kinds of time scales; for the air preheating need, the heat-exchange area of air pre-heater is quite big, which leads to its big thermal inertia, and causes the dynamic process lasting for several ten thousands of seconds.
