PROCEDE DE PILOTAGE DE LA FOURNITURE D'ENERGIE ELECTRIQUE D'UN GROUPE DE PUISSANCE A PILE A COMBUSTIBLE ET DISPOSITIF DE PILOTAGE METTANT EN OEUVRE UN TEL PROCEDE

摘要

The method involves associating a fuel cell (2) to a rechargeable battery (16) that is rechargeable by the fuel cell, and controlling an operation mode of a hydrogen reformer (3) of the fuel cell based on a charge level of the battery. Two operation modes are determined for the reformer, and the respective mode having high power is controlled when the charge level of the battery is lower than a threshold. The respective mode having low power is controlled when the charge level of the battery is higher than another threshold. An independent claim is also included for a device for controlling electrical power supply from a power unit, comprising a control module.
