In the fuel cell vehicle provided with the motor and configured to drive the motor with power of at least one of the fuel celland 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.

Fuel cell vehicle

A vehicle equipped with a fuel cell system is disclosed including a vehicle body having a floor, and a fuel cell system disposed below the floor and including a fuel cell stack and a water supply device connected to a water storage tank. The water supply device includes component elements (a pump, a water supply conduit and a water recovery conduit) that are disposed below the floor of the vehicle body in a higher area than the water storage tank.

Vehicle equipped with fuel cell system

Three ejectorswith differences in specification are connected in parallel between a hydrogen storage unitand a fuel cellRespective ejectorsallow excess hydrogen, discharged from the fuel cellto pass through a hydrogen recirculating common flow passageand to be recirculated through three recirculation branch flow passagesShut-off mechanismsare disposed at both upstream and downstream sides of the respective ejectorswith closing and opening of the shut-off mechanisms located at both the upstream and downstream sides of the respective ejectorspermitting the three ejectorsto be properly used.

Fuel supply apparatus for fuel cell

A fuel cell automobile basically comprises a fuel cell, a cooling system, and a coolant pipe unit. The fuel cell is disposed under a floor panel of a vehicle. The cooling system is configured and arranged to regulate temperature of the fuel cell using a coolant. The cooling system includes at least one cooling system component part that is disposed in a front portion of the vehicle. The coolant pipe unit extends between the fuel cell and the cooling system component part. The coolant pipe unit has a generally horizontal portion disposed in a space under the floor panel and a slope portion extending and sloping continuously upwardly from the horizontal portion to the cooling system component part above the floor panel.

Fuel cell automobile

A vehicle-mounting structure for a fuel cell system of the present invention has a fuel cell, and a hydrogen-related component in which hydrogen to be supplied to the fuel cell flows. In the structure, the fuel cell and the hydrogen-related component are mounted in a space on a front portion in a vehicle body, a hood covering a top opening of the space is inclined downward from a rear side to a front side in the vehicle body, and the hydrogen-related component is placed at a position on the rear side and upper side of the fuel cell in the vehicle body.

Vehicle-mounting structure for fuel cell system

The efficiency of the fuel cell system is increased. This is enabled by controlling a bypass amount of cooling liquid for a conductivity reduction device such as an ion removal device in response to the operating state of the fuel cell system before the conductivity exceeds the permitted limiting value. The device is provided with a recirculation passage which recirculates cooling liquid between a fuel cell and a heat exchanger , a bypass passage having an ion removal filter therein, and a control device which controls solenoids to increase a bypass ratio when the conductivity exceeds the permitted value.

Cooling device for fuel cell system and control method thereof

In a vehicle fuel cell supporting apparatus and method supporting a fuel cell formed by a plurality of unit cells, each of which is provided with an anode, a cathode, and an electrolyte film, and is laminated together with a separator intervening therebetween in a forward and rearward direction of the vehicle, relative movement, in a forward direction of the vehicle, of the cell element located at the front most position of the fuel cell with respect to the vehicle is blocked.

Vehicle fuel cell supporting apparatus and method

A fluid-filled cylindrical elastic mount having an inner sleeve and an outer sleeve, and an elastic body interposed therebetween. The elastic mount also has a primary fluid chamber adapted to undergo pressure changes upon application of a vibrational load to the mount, and a first and a second auxiliary fluid chamber partially defined by a first and a second flexible diaphragm, respectively. The second flexible diaphragm has a greater stiffness than the first flexible diaphragm. A non-compressible fluid flows between the primary and first auxiliary fluid chambers, through a first orifice passage tuned to a first frequency range, and a second orifice passage tuned to a second frequency range that is higher than the first frequency range. The fluid also flows between the primary and second auxiliary fluid chambers, through a third orifice passage tuned to a third frequency range that is higher than the second frequency range. The elastic mount further includes a valve for selectively permitting or interrupting flow of the fluid through the second orifice passage between the primary fluid chamber and the first auxiliary fluid chamber.
