Abstract:

Fuel cell vehicle producing only water as its bye product will serve as a major contributor in reducing greenhouse gas emission by automobile sector. Although it has very good prospects in terms of environmental concern and energy conservation, the complexity lies in the efficient design of cost effective fuel cell vehicle system. These problems should be resolved before fuel cell vehicle system. These problems should be resolved before fuel cell vehicle's mass commercialization. The cost of the vehicle lies in identifying suitalble low cost catalyst similar to the performance of platinum material. The efficiency of fuel cell vehicle lies on the performance of the power drive train system. Due to poor response of fuel cell during the start-up and abnormal load demands, power converters and the control strategy adopted plays a major role in improving the overall performance of the fuel cell vehicle. Although there are enormous new topologies developed for power converters, the analysis of the converters for vehicle dynamics is very few. Hence this research undertakes to design a near optimal fuel cell hybrid electric vehicle. The major focus is on the design of efficacy improved power conditioning unit which comprises of DC-DC converter and DC-AC converter.
