In this paper, a simple multi-closed Proportional-Integral-Derivative (PID) controller is presented for a 5 kW solid oxide fuel cell (SOFC) system. Referring to the presented detailed dynamic model, the external load performance, control parameters and control objectives are studied and discussed. In order to achieve the goal of fast load tracing and high efficiency. Then the designed multi-loop control strategy is introduced and its responses on the external load change and system efficiency are investigated. Results show that the presented multi-loop PID control strategy can not only improve the system efficiency, but also gain the fast tracking of the output power.
