Abstract

La présente invention concerne une technologie permettant à un navire à pile à combustible, qui navigue en utilisant une pile à combustible en tant que source d'énergie, de naviguer dans un lieu comportant une hauteur limite en évitant d'enfreindre la hauteur limite. La navire (1) à pile à combustible, qui navigue en utilisant une pile à combustible (5) en tant que source d'énergie, est pourvu d'un réservoir de carburant (6) pour stocker de l'hydrogène comme combustible fourni à la pile à combustible (5), et est configuré de sorte que le réservoir de carburant (6) est positionné sous l'eau et peut être déplacé verticalement pendant la navigation, la position verticale d'une coque (2) par rapport à la surface de l'eau pouvant être modifiée à mesure que le réservoir de carburant (6) est déplacé verticalement.
