Abstract - The objective of this paper is to present an assessment of cost for a fuel cell hydrogen vehicle (FCV) driven by a brushless DC motor (BLDC). A two leg directly coupled interleaved boost converter is used to power the motor from the fuel cell through a three-phase inverter. The power rating of vehicle motor is calculated and subsequently the rating of the fuel cell is determined. The cost of vehicle components including fuel cell stack, boost converter, brushless DC motor and hydrogen tank is estimated. The cost of FCV, the refueling cost, the market price and the efficiency of FCV are compared with those for internal combustion engine (ICE) and hybrid electric vehicle (HEV). CO2 emission from the conventional ICE and HEV vehicles as well as the CO2 tax are compared with the proposed zero-emission FCV.
