[0030] Referring to FIG. 1, a hydrogen fuel cell vessel (100) according to some embodiments of the present disclosure can rapidly refuel the vessel with hydrogen fuel by separating a hydrogen fuel container (200) from a docked container trailer (900) and loading it into a fuel room (120). In one embodiment, the hydrogen fuel cell vessel (100) does not need to be docked permanently and can be moved during the process of refueling hydrogen fuel using the container trailer (900).

[0031] Referring to FIG. 1, a hydrogen fuel cell vessel (100) according to some embodiments of the present disclosure may be a vessel that sails using a hydrogen fuel container (200) loaded in a fuel room (120) as fuel. Although not illustrated in FIG. 1, in one embodiment, the hydrogen fuel cell vessel (100) may include components for receiving hydrogen from the loaded hydrogen fuel container (200) and using the supplied hydrogen as fuel. For example, the hydrogen fuel cell vessel (100) may include a hydrogen fuel cell for producing power from the supplied hydrogen fuel, a propulsion motor for supplying power to the vessel using the power produced from the hydrogen fuel cell, a receptacle connected to a connector installed in the hydrogen fuel container (200) to receive hydrogen, and a regulator for depressurizing the supplied high-pressure hydrogen and supplying it to the hydrogen fuel cell. Additionally, although not illustrated in FIG. 1, the connector supplying hydrogen from the hydrogen fuel container (200) and the manifold installed on the vessel may be connected by a flexible line using a bidirectional high-pressure quick connector type. The components described above are exemplary, and components necessary to produce power for the vessel using hydrogen fuel should also be considered to be included in the content of this disclosure.

As will be described later in FIGS. 3 and 4, the fuel chamber (120) may be formed using one or more partitions and separated from the outside of the fuel chamber. In one embodiment, the partitions constituting the fuel chamber may be implemented with different structures.

[0034] In some embodiments, the fuel chamber (120) may further include components for securely securing stacked hydrogen fuel containers (200). For example, the fuel chamber (120) may securely secure the hydrogen fuel containers (200) during operation using cell guides and / or twist locks. Additionally, one or more bulkheads constituting the fuel chamber (120) may protect the hydrogen fuel containers (200) from waves and / or hazardous conditions at sea that may occur during the operation of the hydrogen fuel containers (200).

[0035] A hydrogen fuel container (200) according to some embodiments of the present disclosure may be a hydrogen carrier in the shape of a container having fixed dimensions. In one embodiment, the hydrogen fuel container (200) may include a hydrogen tube. Preferably, the hydrogen fuel container (200) may be constructed according to ISO 668 standards. In some embodiments of the present disclosure, the hydrogen fuel container (200) may be transported using a container trailer (900). Preferably, the container trailer (900) may transport a plurality of hydrogen fuel containers (200) simultaneously. In one embodiment, the container trailer (900) may dock and approach the hydrogen fuel cell vessel (100), and the hydrogen fuel container (200) may be separated from the container trailer (900). A crane (110) of the hydrogen fuel cell vessel (100) may move the separated hydrogen fuel container (200) to the fuel room (120) of the hydrogen fuel cell vessel (100) for loading.

[0036] In one example, a hydrogen fuel cell vessel (100) can load hydrogen fuel containers (200) into a fuel room (120) at multiple docking locations. For example, the hydrogen fuel cell vessel (100) can load a first hydrogen fuel container separated from a first container trailer into the fuel room (120) at a first docking location, then move to load a second hydrogen fuel container separated from a second container trailer into the fuel room (120) at a second docking location.
