Conception d'une source hybride utilisant une pile à combustible et des supercondensateurs :

Abstract : The design and testing of a purely supercapacitor energy storage device as auxiliary power source in electrical vehicle applications having a PEM fuel cell as main source are presented. Two control strategies are explained to operate in almost steady state conditions in order to lessen the mechanical stresses of fuel cell and to ensure a good synchronization between fuel flow and fuel cell current. Supercapacitors are functioning during absence of energy from fuel cell, transient energy delivery or transient energy recovery. The system utilizes two modules of supercapacitive storage device connected to the DC bus by a 2-quadrant dc/dc converter. The system structure is realized by analogical current loops and digital control for voltage loops and estimation algorithms. Experimental results with a 500 W PEM fuel cell point out the slow dynamics of fuel cell, and also substantiate that the supercapacitors can improve dynamics and power conditioning for automotive electrical system
