Abstract:

Fuel cell vehicles have the potential to address the problems surrounding the ICE vehicle without imposing any significant restrictions on vehicle performance, driving range, or refuelling time. Though there are currently some obstacles to overcome before attaining the widespread commercialization of fuel cell vehicles, such as improvements in fuel cell and battery durability, development of a hydrogen infrastructure, and reduction of high costs, the fundamental concept of the fuel cell vehicle is strong: it is efficient, emits zero harmful emissions, and the hydrogen fuel can be produced from various renewable sources. Therefore, research on fuel cell vehicle design is imperative in order to improve vehicle performance and durability, increase efficiency, and reduce costs. In this research work the resonant bidirectional full bridge dcdc converter with phase shifted pulse width modulation technique is implemented for a fuel cell electric vehicle. This thesis makes a number of key contributions to the advancement of fuel cell vehicle design within two main research areas: Power backup during the regenerative mode and analysis of State of Charge (SoC) of battery with the various controllers.
