Dynamic interaction between the electric drive train and fuel cell system for the case of an indirect methanol fuel cell vehicle

This paper examines the impact of the drive system and fuel cell system characteristics as well as the dynamic interaction between the electric drive train and the fuel cell system of an indirect-methanol fuel cell vehicle (FCV) on vehicle performance. First, simple models for the electric drive train and the fuel cell system will be explained. Second the interaction of the two models is illustrated. Third the effect of parameter variations on the vehicle acceleration from 0-60 mph (ca. 0-100 kph) is analyzed. For this the sub-models for the drive train and the electric motor will be embedded in a vehicle model.
