Zusammenfassung:	If a main stop valve of a fuel gas tank is not opened, it becomes possible to display a remaining level of fuel gas. A remaining fuel level displaying method for the fuel cell system comprises: if the main stop valve is opened, then calculating a remaining level of fuel gas in the fuel gas tank using a pressure value acquired from the pressure sensor, and displaying the calculated remaining level of the fuel gas on a display device, and if the main stop valve is closed, then displaying on the display device a remaining level of the fuel gas that was stored into a memory at a time when the main stop valve was shut off. Si une soupape darrêt principale dun réservoir de gaz combustible nest pas ouverte, il devient possible dafficher le niveau de gaz combustible restant. Une méthode daffichage du niveau de gaz combustible restant destiné à un mécanisme de pile à combustible comprend ceci : si la soupape darrêt principale est ouverte, calculer un niveau de gaz combustible restant dans le réservoir de gaz combustible à laide dune valeur de pression obtenue auprès du capteur de pression et afficher le niveau de gaz combustible restant calculé sur un dispositif daffichage; et, si la soupape darrêt principale est fermée, afficher sur le dispositif daffichage un niveau de gaz combustible restant qui avait été gardé en mémoire au moment où la soupape darrêt principale avait été fermée.
