A pressure vessel for the storage of pressurized fluids for a fuel cell system, a liner for the pressurized vessel and a method of making. The method of manufacturing a pressure vessel includes forming a lost core assembly, a reinforcement structure around the assembly and removing the core from said assembly to define an internal compartment. The lost core assembly includes a first sacrificial material used to define the shape of the pressure vessel's internal compartment, boss attachable to the first material for the introduction and removal of the fluid into the pressure vessel, and a second material for placement around the first material and at least a portion of the boss such that upon removal of the first material, the second material defines the liner. The reinforcement structure is wound around the liner to give the pressure vessel a unitary, composite structure.

A fuel cell vehicle includes a fuel cell stack, a fuel tank, a body-side mounting portion, a main fuel pipe, a securing mechanism, and an elastic pipe. The fuel cell stack is disposed in a front section of the fuel cell vehicle. The fuel tank is disposed in a rear section of the fuel cell vehicle. The main fuel pipe connects the fuel tank and the body-side mounting portion. The elastic pipe is connected to the fuel cell stack at a first end of the elastic pipe and connected, via the securing mechanism, to the body-side mounting portion at a second end of the elastic pipe opposite to the first end such that the second end of the elastic pipe is disengaged from the body-side mounting portion when a load larger than a predetermined threshold load is applied to the securing mechanism.

Some embodiments include a mobile fueling system. The mobile fueling system includes a fueling lid configured to cover a fueling compartment opening, and a recessed fueling compartment having the fueling compartment opening. The recessed fueling compartment includes one or more compartment walls having at least one recessed wall portion that is recessed a predetermined distance away from the fueling compartment opening, with the one or more compartment walls defining an interior compartment volume. The recessed fueling compartment further includes a fueling port configured to couple the recessed fueling compartment to a fuel storage tank, and a gas inlet in at least one of the one or more compartment walls of the recessed fueling compartment. The gas inlet is configured to introduce a gas into the interior compartment volume. Other embodiments of related systems and methods are also disclosed.

A transport vehicle configured to run on electricity generated by a fuel cell includes: a body having a cargo space for freight; a chassis frame located below the body and supporting the body; and a tank unit including a plurality of tanks that stores fuel gas to be used for power generation by the fuel cell and a connecting portion connecting the tanks, the tank unit being located between the cargo space and the chassis frame.

The present application discloses a hydrogen station for supplying hydrogen to a tank of a tank-equipped device. The hydrogen station includes: an integrated controller for integrally controlling devices provided in the hydrogen station; a sensing portion for sensing leaked hydrogen which has leaked inside the integrated controller; a ventilation device performing a high ventilation measure of performing ventilation for air inside the integrated controller or an explosion prevention device performing an internal pressure-based explosion protection measure of creating a pressure-increased state inside the integrated controller; and a compressor unit including a compressor, which is used as one of the devices, and a housing, in which the compressor is stored. The integrated controller is mounted on the housing, and is electrically connected to the compressor via a through-hole formed in the housing to control the compressor.

A high-pressure hydrogen tank includes a metal circular cylinder configured to store high-pressure hydrogen therein, a cap part configured to cover each of opposite end portions of the metal circular cylinder, an outer cylinder surrounding an outer periphery of a circular-cylindrical portion of the metal circular cylinder, and a fastening part configured to fix the cap part to the outer cylinder.

A gas sensor includes a gas detecting element that includes a first electrode, a metal oxide layer, and a second electrode; and a first insulating film that has an opening allowing the second electrode to be partially exposed therethrough and covers the first electrode, the metal oxide layer, and another part of the second electrode. The metal oxide layer has a characteristic where its resistance value changes as the second electrode makes contact with gas molecules including hydrogen atoms. A first step is provided at a portion lying on an interface between the metal oxide layer and the second electrode and located within the opening as viewed in plan view. A local region is provided in the metal oxide layer and near the first step. A degree of oxygen deficiency of the local region is greater than a degree of oxygen deficiency of other regions in the metal oxide layer.

A drainage portion extending from one to the other of a bottom wall of a recess and a lid is provided at least above a hydrogen filling port in the recess when the lid is in a closed state. Therefore, water, which has entered the recess from a gap (parting) when the lid is in a closed state, reaches an upper surface of the drainage portion and flows along the upper surface of the drainage portion, and then, the water flows down from the drainage portion while avoiding the hydrogen filling port. Accordingly, it is possible to suppress the water having entered the recess while the lid is in a closed state from adhering to the hydrogen filling port.

To provide a filling apparatus capable of suppressing radial movement of a rod-shaped member (connecting pin) of a nozzle, and preventing damages and deformations (recesses and so on) from generating on an outer peripheral surface of the connecting pin. A filling apparatus (100) according to the present invention includes: a storage tank for storing hydrogen fuel; a filling nozzle (10) for filling a hydrogen gas from the storage tank through a fuel filling system to an in-vehicle hydrogen filling tank mounted on a vehicle; a rod-shaped member (2: connecting pin) and a main body portion (1) mounted on the filling nozzle (10); a sealing member (3: laminated sealing member) arranged on (a radially outer peripheral portion of the rod-shaped member of) the main body portion (1); a guide member (4: pressing member), projecting radially inward, mounted on a portion separated from an end side of the rod-shaped member (2) (from a receptacle 20 side in an in-vehicle hydrogen filling tank to the fuel filling system); and means for protecting an outer peripheral surface of the rod-shaped member (2) from slide on the guide member (4).
