Fuel cell and battery hybridization for automotive application

Abstract : In 2006, a fuel cell technology was developed between CEA and PSA in France. The first design is a 80 kW one for a 65 kW automotive power train. Theses specifications are adapted for a fuel cell vehicle without power battery hybridation. Now, in our different applications, the fuel cell system is designed with hybridation with a Lithium ion power battery. A first example is electric vehicle with about 100 km range with the battery electricity and a fuel cell range extender which is designed for mean power and not for maximum power. Another example is the use of a fast charge and discharge high power lithium ion battery with a very good intrinsic security. With this kind of battery, it's possible to use the stored electricity and to recharge very quickly the battery due to the fast charge.
