Fuel cell vehicles promise to be far more efficient, produce low or zero emissions, and operate cleaner than conventional vehicles. Main components of a fuel cell propulsion system are: reformer, fuel cell stack, DC/DC converter, battery, inverter, and the drive motor. Alternatively, the vehicle can be configured with or without the reformer and with or without the battery pack. This paper discusses these alternative fuel cell vehicle configurations and the control strategies for each of these configurations. The advantages and limitations of the alternatives are also presented. The concept strategies for operating the DC/DC converter to make the output of the fuel cell stack compatible with the input requirements of the inverter in order to control the motor over a wide speed and torque range are outlined. The propulsion system and control issues, the power electronics issues, and selection of the rotating machines for a fuel cell vehicle are discussed.
