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.
