Title
(EN) FUEL CELL SYSTEM
(FR) SYSTÈME DE PILE À COMBUSTIBLE
Abstract
(EN)
To provide a fuel cell system capable of controlling a fuel cell at a time of startactivation and at a time of stopsuspension with a simple structure while controlling an influence of an outside air temperature in a use environment, the present fuel cell system includes a fuel cell including a power generating portion including a fuel electrode and an oxidizer electrode, for performing power generation based on a fuel supplied from a fuel tank; and a switch provided between the fuel electrode and the oxidizer electrode so as to switch connection and disconnection of a resistor between and with the fuel electrode and the oxidizer electrode, wherein the switching of the connection and disconnection of the resistor by the switch is performed based on at least one temperature difference between two of the power generating portion of the fuel cell, the fuel tank and outside air.
(FR)
Afin de parvenir à un système de pile à combustible capable de commander une pile à combustible lors d'une activation de démarrage et lors d'une suspension d'arrêt, à l'aide d'une structure simple, tout en régulant l'influence de la température de l'air extérieur dans un milieu d'utilisation, le présent système de pile à combustible comprend : une pile à combustible équipée d'une partie génératrice de puissance dotée d'une électrode à combustible et d'une électrode à oxydant ; et un interrupteur installé entre l'électrode à combustible et l'électrode à oxydant, afin de pouvoir connecter et déconnecter une résistance entre et avec l'électrode à combustible et l'électrode à oxydant, le passage entre la connexion et la déconnexion de la résistance à l'aide de l'interrupteur étant effectué sur la base au moins d'une différence de température entre deux éléments parmi la partie génératrice de puissance de la pile à combustible, le réservoir de combustible et l'air externe.
