A fuel cell electric vehicle includes: a motor, a fuel cell stack and an integrated controller, which are accommodated in a PE room provided in a front of a vehicle body; a battery assembly including a high-voltage battery electrically connected to the motor and the fuel cell stack, and a low-voltage battery for supplying electric power to a vehicle electrical part; an IDC that is mounted between the PE room and the battery assembly, and electrically connects the high-voltage battery to the motor and the fuel cell stack; and a plurality of hydrogen tanks that is mounted at a rear of the battery assembly and below the vehicle body. In particular, the battery assembly is mounted at a rear of the PE room and below the vehicle body, and the IDC converts power of the high-voltage battery to be supplied to the low-voltage battery.

A system control method is provided for measuring a distance between a smart key and a vehicle. When the distance between the smart key and the vehicle is changed based on a predetermined distance whether a hydrogen leak occurs is detected by a hydrogen sensor detection controller. A driver is then informed of a hydrogen leak via a display on a cluster, a turn-on of an emergency light, and a warning sound of the vehicle. Alternatively, a starting-impossible state of the vehicle or shutting-down starting of the vehicle is maintained to ensure safety measures based on the concentration of the leaking hydrogen.

In order for a vehicle to which a fuel cell module is mounted to fully secure an electric connection between a vehicle body and the fuel cell module, a vehicle is provided, which includes a conductive plate-like member, constituting at least a part of a floor portion of a vehicle body of the vehicle, and having a protruded portion protruded upwardly in the gravity directions and extended from the front to the rear of the vehicle, a fuel cell module, provided downward in the gravity directions from the plate-like member, and accommodating a fuel cell, and a grounding wire, electrically connecting the fuel cell module with the plate-like member within a range when seen in the gravity direction where the protruded portion exists.

A required output (power consumption amount) of each of loads to which electrical power generated by fuel cell stacks is supplied is adjusted, in a manner so that a difference in a residual amount of fuel in the fuel tanks between fuel cell engines is reduced.

An embodiment fuel cell vehicle includes a fuel cell, a power distributor disposed on the fuel cell and configured to receive power generated by the fuel cell, a voltage cable connected to a rear side of the power distributor, and a cable bumper coupled to the rear side of the power distributor and surrounding a portion of the voltage cable.

A multipurpose vehicle system with interchangeable operational components and power supplies is operational in multiple operational modes. The operational modes include: a personal transport vehicle mode, a service vehicle mode, and a commercial vehicle mode. The vehicle system has a dimensionally adjustable chassis module. The chassis module has the capacity to detachably attach to multiple exterior, interior, motor, and transmission components. The chassis module supports a cabin module and a rear module that enables formation of different iterations of vehicles. The vehicle system provides multiple different and interchangeable power supplies, like a rechargeable battery and a hydrogen tank. The power supplies are interchangeable. The used components can be recycled and interchanged with new components. The vehicle system also comprises at least one autonomous trailer that comprises a receiver in communication with a transmitter in the chassis module, allowing the autonomous trailer to be remotely towed by the chassis module.

In the fuel cell vehicle provided with the motor and configured to drive the motor with power of at least one of the fuel cell 1 and the battery, the fuel cell having a DC voltage of less than 60 V is disposed in the rear portion of the vehicle and the battery is disposed in the front relative to the fuel cell.

There is provided a fuel cell vehicle that allows minimally suppressing damage of a fuel cell stack and a high voltage component as important components when the vehicle collides from a front side. An ion exchanger as a first component includes a tubular portion and a cap portion. When the front side of the fuel cell vehicle collides, the tubular portion deforms due to an impact load from a radiator as a second component moving toward the ion exchanger to buffer an impact from the radiator. The cap portion restricts additional deformation of a damper portion when the impact load from the radiator becomes a predetermined magnitude or more. A stack frame and a chassis are joined and fixed via mounts such that the stack frame is detached from the chassis due to the impact load from the radiator when the deformation of the tubular portion is restricted by the cap portion.
