A fuel cell vehicle includes: a fuel cell; a storage portion to store produced water that is produced as a result of power generation by the fuel cell; a drainage valve for switching between a storage state and a drainage state of discharging the produced water from the storage portion to the outside of the fuel cell vehicle; a road information acquisition portion configured to acquire road information on roads on which the fuel cell vehicle travels; and a controller configured to drainage valve control operation. The controller sets a road region meeting a first condition defined in advance regarding road information and that permits the drainage state as a first road region where the drainage state is permitted, and the controller performs drainage if a drainage implementation condition defined in advance, including traveling of the fuel cell vehicle in the first road region, is fulfilled.

Fuel cell vehicle

A fuel cell vehicle mounted with a fuel gas tank in an underfloor of the vehicle. The fuel cell vehicle includes: a floor that has a projecting portion projecting upward in a height direction of the vehicle and extending along a front and rear direction of the vehicle; a fuel gas tank arranged under the projecting portion in the height direction of the vehicle and fixed to the floor; and an undercover arranged under the fuel gas tank in the height direction of the vehicle. The undercover has a fixation protruded portion that projects upward in the height direction of the vehicle in a side of the fuel gas tank in a width direction of the vehicle, and being fixed to the floor by the fixation protruded portion.

There is provided a fuel cell vehicle equipped with a fuel cell. The fuel cell vehicle comprises a fuel gas supply piping located in floor of the fuel cell vehicle and configured to supply a fuel gas to the fuel cell; an exhaust drainage piping located under the floor and configured to discharge an exhaust gas and water from the fuel cell; a muffler located below the fuel gas supply piping in a direction of gravity and connected with the exhaust drainage piping; and an undercover located below the muffler and provided to cover the floor, the undercover having a gap along a front-rear direction of the fuel cell vehicle formed between a front wheel of the fuel cell vehicle. The muffler is placed on any straight line that passes through the fuel gas supply pipe and that connects any point of a contact area in which the front wheel is in contact with ground surface with the gap in a view of a left-right direction of the fuel cell vehicle.

A fuel cell vehicle includes a fuel cell stack, a tank, a discharge flow path discharging a fluid discharged from the fuel cell stack, a muffler attached to the discharge flow paths, and a vehicle member defining a first chamber and a second chamber, the first chamber accommodating the fuel cell stack and the second chamber being disposed behind the first chamber and accommodating the tank and the muffler. The second chamber is also provided with a front portion and a rear portion continuous with the front portion, the rear portion being shorter than the front portion in average length in a vehicle width direction. The muffler is disposed between the tank and one of a pair of side wall portions defining side walls of the front portion in the vehicle width direction.

In order to limit entry of a fuel cell stack into a passenger compartment by a simple structure, the fuel cell stack is accommodated in an accommodating compartment formed at a rear of a passenger compartment. A force receiving member is arranged forward with respect to the fuel cell stack and below the fuel cell stack so that rearward force acts on the force receiving member at the time of vehicle collision. When the rearward force acting on the force receiving member due to vehicle collision is larger than a predetermined upper limit value, the rearward force is converted into upward force, and the upward force is transmitted to a forward bottom surface of the fuel cell stack, whereby a forward end part of the fuel cell stack is lifted up with respect to a rearward end part of the fuel cell stack upon vehicle collision.

Electric vehicle

A holding mechanism includes: a holding plate capable of holding an electronic device for an electric vehicle; a leg portion supporting two long sides of the holding plate; first and second fixing portions provided in the leg portion and separated from each other in a short direction of the holding plate; and a third fixing portion located at or near one of two sides of the holding plate along the short direction and located higher than the first and second fixing portions, wherein the first and second fixing portions can be respectively fixed to first and second mount parts provided in a vehicle body structural member at a front side of the electric vehicle and separated from each other in a width direction or front-rear direction of the electric vehicle, and the third fixing portion can be fixed to a third mount part provided in the vehicle body structural member.

Rear-drive electric vehicle

A fuel cell vehicle comprises a front room; a vehicle interior; a fuel cell in the front room; a center tunnel; a tank that is at least partly placed in the center tunnel and stores a gas to be supplied to the fuel cell; and a dashboard that separates the front room from the vehicle interior, wherein the fuel cell is placed above the tank such that a profile of the fuel cell does not overlap with a center axis of the tank, the dashboard has an overlapping portion arranged to overlap with a rear portion of the fuel cell and that is located behind a front end of the tank, at least part of a remaining portion of the dashboard other than the overlapping portion is placed flush with the front end of the tank in a vehicle longitudinal direction or is placed in front of the front end of the tank, and in a normal state, a receiving space is provided between a rear end of the fuel cell and the overlapping portion and is configured to allow at least part of the rear portion of the fuel cell to be moved to behind the front end of the tank when the front collision occurs.

Front-drive electric vehicle

A compressor, an intercooler, and a fuel cell stack are housed in a housing compartment. The compressor and the intercooler are connected with each other by upstream side piping, and the intercooler and the fuel cell stack are connected with each other by downstream side piping. The upstream side piping is formed from upstream side first and second pipe parts, and the downstream side piping is formed from downstream side first and second pipe parts. Movement of the compressor and fuel cell stack relative to the intercooler at the time of a heavy collision of the vehicle causes disconnection of the upstream side first and second pipe parts and disconnection of the downstream side first and second pipe parts, to thereby cause communication of the upstream side piping and the downstream side piping with an internal space of the housing compartment.

This electrode for fuel cell comprises: carbon nanotubes; a catalyst for fuel cell supported on the carbon nanotubes; and an ionomer provided to coat the carbon nanotubes and the catalyst for fuel cell, wherein when a length of the carbon nanotubes is represented by La [&#x3bc;m] and an inter-core pitch of the carbon nanotubes is represented by Pa [nm], the length La and the inter-core pitch Pa satisfy two expressions given below: 30&#x2266;La&#x2266;240; and 0.351&#xd7;La+75&#x2266;Pa&#x2266;250.
