Title (EN) FUEL CELL SYSTEM, CONTROL METHOD FOR THE FUEL CELL SYSTEM, AND ELECTRIC VEHICLE EQUIPPED WITH THE FUEL CELL SYSTEM
(FR) SYSTÈME DE PILE À COMBUSTIBLE, PROCÉDÉ POUR SYSTÈME DE PILE À COMBUSTIBLE ET VÉHICULE ÉLECTRIQUE ÉQUIPÉ DUDIT SYSTÈME DE PILE À COMBUSTIBLE
Abstract:
(EN) A fuel cell system (100) that includes a fuel cell (11) that generates electricity through an electrochemical reaction between a fuel gas and an oxidant gas, and a control portion (50) that determines whether there is leakage of the fuel gas. The control portion has start means for starting the fuel cell by raising the voltage of the fuel cell from a starting voltage to an operation voltage that is lower than an open-circuit voltage, and leakage determination means for determining whether there is leakage of the fuel gas before the voltage of the fuel cell reaches the operation voltage when the fuel cell is started.
(FR) L'invention concerne un système de pile à combustible (100) comprenant une pile à combustible (11) qui génère de l'électricité par réaction électrochimique entre un gaz combustible et un gaz oxydant, et un module de commande (50) qui détermine s'il existe une fuite de gaz combustible. Le module de commande comprend un moyen de démarrage pour démarrer la pile à combustible en élevant la tension de la pile à combustible d'une tension de départ à une tension de fonctionnement laquelle est inférieure à une tension en circuit ouvert, et un moyen de détection de fuite pour déterminer s'il existe une fuite de gaz combustible avant que la tension de la pile à combustible n'atteigne la tension de fonctionnement lors de son démarrage.
