Résumé

A fuel cell vehicle is primarily an electric vehicle. The motorization is provided by one or more electrical machines and the power is supplied by the fuel cell system. Since the production of electrical energy is carried out without greenhouse gas emissions, a fuel cell vehicle is considered non-polluting (locally). In the context of automobile use, the fuel cell is therefore generally assisted by a secondary source of electrical energy. This type of vehicle is then called a "fuel cell hybrid vehicle".
Hybridization distributes the power demand between the fuel cell system and the secondary energy source. The operating points of the fuel cell system can thus be shifted to higher yield areas by using appropriate control strategies, thereby reducing hydrogen consumption. The secondary source can be recharged by kinetic energy recovery or by the fuel cell system. In a fuel cell vehicle, two technologies are generally retained to form the secondary source of energy: batteries and super-capacitors. The fuel cell and hydrogen have the highest specific capacity, followed by batteries and super-capacitors. Conversely, super capacitors have the largest specific power, followed by batteries and fuel cells. Both technologies have very different characteristics. Some authors favor the use of super-capacitors because of their energy efficiency and specific power, but their low capacity can be a handicap. Conversely, batteries are able to store a large amount of energy but are penalized by their specific power. One solution is to couple batteries and super-capacitors to combine their advantages (power and energy).
Keywords— Fuel Cell Vehicles; Fuel Cell; Secondary source of energy; Battery; Super-capacitors; Specific Power; Specific Energy.
