The fuel cell powered vehicle is one of the most attractive candidates for the future due to its high efficiency and capability to use hydrogen as the fuel. However, its relatively poor dynamic response, high cost and limited life time have impeded its widespread adoption. With the emergence of large supercapacitors (also know as ultracapacitors, UCs) with high power density and the shift to hybridisation in the vehicle technology, fuel cell/supercapacitor hybrid fuel cell vehicles are gaining more attention. Fuel cells in conjunction with supercapacitors can create high power with fast dynamic response, which makes it well suitable for automotive applications. Hybrid fuel cell vehicles with different powertrain configurations have been evaluated based on simulations performed at the Institute of Transportation Studies, University of California-Davis. The following powertrain configurations have been considered: (a) Direct hydrogen fuel cell vehicles (FCVs) without energy storage, (b) FCVs with supercapacitors directly connected in parallel with fuel cells, (c) FCVs with supercapacitors coupled in parallel with fuel cells through a DC/DC converter, (d) FCVs with fuel cells connected to supercapacitors via a DC/DC converter.
