ABSTRACT

This chapter discusses the Fuel cell vehicle (FCV) components, and presents a hybrid fuel cell system design and control for electric vehicles. It focuses on the fuel cell subsystems—gas flow management, water management, and heat management system. Fuel cell powered vehicle uses the hydrogen fuel as the major source of electric power to drive its electric traction motor through a fuel cell system. The power demand of an FCV’s electric motor ranges from 75 to 120 kW. With great progress in power electronics and microcontroller-based controllers, compact, cost-effective, and highly efficient inverters make it possible for an alternating current induction motor and brushless permanent magnet motor to be able to be utilized in FCVs. Auxiliary systems in FCVs such as pumps, air conditioning, various sensors, and gauges in the electric drive systems can work at the voltages of 12 V, 140 V, 300 V, or the standard voltage of 42 V.
