Solid oxide fuel cell (SOFC) has been identified as an effective and clean alternative choice for marine power system. This
paper emphasizes on the dynamic modeling of SOFC power system and its performance based upon marine operating circumstance.
A SOFC power system model has been provided considering thermodynamic and electrochemical reaction mechanism. Subcomponents
of lithium ion battery, power conditioning unit, stack structure and controller are integrated in the model. The dynamic response
of the system is identified according to the inertia of its subcomponent and controller. Validation of the whole system simulation
at steady state and transit period are presented, concerning the effects of thermo inertia, control strategy and seagoing
environment. The simulation results show reasonable accuracy compare with lab test. The models can be used to predict performance
of a SOFC power system and identify the system response when part of the component parameter is adjusted. 相似文献
