Provided is an electric vehicle in which impacts on a high-voltage connector from at least one of a dashboard or a cowl member can be suppressed. The electric vehicle includes a case disposed ahead of the dashboard and the cowl member of the vehicle, the case being adapted to house a high-voltage component, a high-voltage connector disposed on the upper face of the case and connected to the high-voltage component; and an auxiliary unit disposed on the upper face of the case. The auxiliary unit is disposed closer to the dashboard than is the high-voltage connector, and is formed of a material with higher rigidity than those of the dashboard and the cowl member.

A fuel cell-equipped vehicle includes a fuel cell stack disposed in a front space of a vehicle body by a partition member, and an air conditioner disposed in a rear space of the vehicle body separated by the partition member, wherein external air is introduced into the air conditioner through an external air intake port formed at a portion of the partition member located on a first side with respect to a center in a vehicle width direction of the vehicle body, downstream end of the exhaust duct configured to discharge a reaction gas in the casing communicates with an outside of the vehicle body at a portion located on a second side with respect to the center in the vehicle width direction.

The fuel cell vehicle includes a housing case having a stack housing portion that houses a fuel cell stack, and a high voltage component housing portion that houses a high voltage component, is disposed above the stack housing portion, and allows gas to be circulated to and from the stack housing portion; and pressure relief mechanisms provided on the front, rear, left, and right side walls respectively. A front side pressure relief mechanism is disposed in a position facing a radiator support, a left side pressure relief mechanism is disposed in a position facing an apron member and suspension tower on the left side, a rear side pressure relief mechanism is disposed in a position facing a dash panel and cowl member, and a right side pressure relief mechanism is disposed in a position facing an apron member and suspension tower on the right side.

A fuel cell system that ensures restraining a pressure relief mechanism from scattering is provided. The fuel cell system includes: a housing case that includes a stack housing portion housing a fuel cell stack and a high voltage component housing portion housing a high voltage component; a front side pressure relief mechanism, a left side pressure relief mechanism, a rear side pressure relief mechanism, a right side pressure relief mechanism, and an upper side pressure relief mechanism disposed on the high voltage component housing portion; and an auxiliary machine disposed outside the high voltage component housing portion. The respective pressure relief mechanisms are disposed in positions opposed to the auxiliary machine so as to have clearances with the auxiliary machine, and have rigidities lower than the rigidity of the auxiliary machine.

An electricity-generating system is configured to be carried on a trailer having a chassis. The electricity-generating system is of modular construction and includes a fluid storage module including a fluid storage device, and an electricity-generating module including an electricity-generating device configured to produce electricity from the fluid or fluids stored in the fluid storage device. The fluid storage module and the electricity-generating module are configured to be mounted on the chassis of the trailer. The fluid storage module is configured to be mounted in a removable manner on the chassis separately from the electricity-generating module.

A fuel cell vehicle includes: a cab floor formed higher at a rear portion than at a front portion by a step portion obliquely inclined upward and rearward in a vehicle length direction; and a fuel cell system disposed below the cab floor, the fuel cell vehicle being configured to travel using electric power generated by the fuel cell system, in which the rear portion of the cab floor has a shape for accumulating fuel leaking and ascending from the fuel cell system.
