A Distributed Real-Time Control System for PEM Fuel Cell Engine

A real time distributed control system for a 100Kw PEM fuel cell engine will be presented in this paper. The fuel cell engine is successful applied to a demonstration city bus in Beijing city for the Olympic Games. The framework of the control system, which is based on the Time Trigger Controller Area Network (TTCAN), will be presented in this paper. The control task schedule and optimize of TTCAN are analyzed. The individual and flexible output power control of the FC blocks is discussed and then the improved solution is presented.
