A fuel cell vehicle includes a fuel cell, a storage device, a receptacle, a housing, and a vehicle side communication device. The housing has a bottom wall recessed from a surface of a body of the fuel cell vehicle by a predetermined depth. The receptacle protrudes from a bottom face of the bottom wall to an inner space of the housing. The vehicle side communication device is provided to the housing on an outer circumferential side of the receptacle. The vehicle side communication device is configured to wirelessly communicate with a nozzle side communication device provided to a nozzle. The vehicle side communication device is disposed on a deeper side than the bottom face of the bottom wall and/or is disposed via a partition wall configured to shield the vehicle side communication device from fuel gas in the inner space.

A fuel cell vehicle includes a fuel cell stack, a fuel tank that stores fuel gas to be supplied to the fuel cell stack, a tank chamber that houses the fuel tank, a gas filling port that fills the fuel tank with fuel gas from outside of the vehicle, a filling lid box that includes a housing chamber and a lid member and is provided above the tank chamber, a fuel gas sensor that is arranged in the tank chamber, and a duct that allows the housing chamber and the tank chamber to communicate with each other.

A fuel cell vehicle insulation resistor fault detection system, comprising: a stack, a stack pre-charge circuit, a power cell, a power distribution controller, a high voltage component, a VCU (vehicle control unit) and at least one insulation detector. The stack is connected to the stack pre-charge circuit, the stack pre-charge circuit is connected to the power cell, the power cell is connected to the power distribution controller, the power distribution controller is connected to the high voltage component and the VCU is connected to the insulation detector. When the insulation detector is used to detect whether the insulation resistor of the stack is faulty, the stack is connected to the insulation detector; when the insulation detector is used to detect whether the insulation resistor of the power cell is faulty, the power cell is connected to the insulation detector; and when the insulation detector is used to detect whether the insulation resistor of the high voltage component is faulty, the power distribution controller is connected to the insulation detector. When an insulation resistor of the fuel cell vehicle is faulty, the source of the insulation resistor fault can be located in time.

A vehicle fuel cell stack includes a stacked body, a stack case, and a cover member. The stack case accommodating the stacked body therein. The stack case includes an upper wall, a lower wall, and a vent opening. The lower wall is opposite to and below the upper wall in a height direction of a vehicle. The lower wall includes an upper surface and a lower surface opposite to and below the upper surface in the height direction. The vent opening passes through the bottom wall in the height direction. The cover member is disposed on the lower surface of the bottom wall to cover the vent opening when viewed in the height direction and to have an opening between the cover member and the lower surface of the bottom wall when viewed along the lower surface.

A fuel cell vehicle which a fuel cell stack is mounted on comprises a stack case that is configured to place the fuel cell stack therein; mounts that are configured to fix the stack case to a vehicle body; ribs, each being provided to be extended from a position adjacent to the mount across an upper surface of the stack case; and a damping member that is provided between adjacent ribs on the upper surface of the stack case. The damping member is a material formed by applying an aluminum sheet on butyl rubber. This configuration reduces the noise and damps the vibration.

The disclosure relates to a body structure element for increasing the stiffness and/or the crash performance of a body structure of a vehicle, comprising a first channel for a first gas flow with a first gas feed line and a first gas discharge line and comprising means for introducing moisture into the first gas stream. The disclosure relates, in other words, to the functional integration of a humidifier for a fuel cell system into a body structure element and preferably the functional integration of a humidifier for a fuel cell system into crash performance increasing element, in particular, an extrusion profile, and a body structural element. The disclosure also relates to a fuel cell system with a humidifier integrated into a body structure element and a vehicle with such a fuel cell system and/or such a body structure element.

A fuel cell system includes a fuel cell stack and a stack case. Curved portions are formed at corners of a first end plate. An upper plate includes curving sections facing the curved portions of the first end plate. An upper seal member is partially interposed between the curved portions of the first end plate and the curving sections of the upper plate.

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.

A fuel cell stack includes a bracket and a boss. The bracket includes an attachment surface. The bracket includes an attachment and detachment hole and an opening hole. The boss includes a bearing surface and a locking surface part. The locking surface part is connected to the bearing surface and protrudes in an outside direction such that at least a part of the locking surface part overlaps with the attachment surface part viewed from an attachment direction when a center of the attachment and detachment hole coincides with a center of the bearing surface.

A fuel cell two-wheeled vehicle includes an electric machine configured to drive a drive wheel, an air-cooled fuel cell configured to supply electric power to the electric machine, and a fuel gas tank that accumulates fuel gas supplied to the fuel cell. A battery pack is disposed in a space between an intake air inlet and an air intake duct and surrounded by a seat and a vehicle body cover. The intake air inlet is disposed below a front portion of the seat.
