Driving the automobiles with a power generating unit other than an IC Engine is one of the main focus areas of present day Advanced Vehicle Engineering research. In this regard, the use of a fuel cell in combination with a power converter and motor as an alternative to the IC Engine as the primary power source for an automobile is very attractive. This thesis develops model of a series hybrid vehicle with a PEM fuel cell as its Auxiliary Power Unit (APU). Simulation using the model helps to provide an understanding of the interaction and flow of power. Moreover, electrical power sharing between the APU and the Electrical Storage System (ESS) is shown. Conclusions and scope of future work are also discussed.
