Abstract
To provide a drainage structure for a fuel cell electric vehicle wherein gas exhausted from a fuel cell is exhausted into the air via a muffler and generated water from the fuel cell can be moderately exhausted. In a drainage structure is provided for a fuel cell electric vehicle that includes a fuel cell for generating electric power by reacting hydrogen and oxygen, a hydrogen cylinder for supplying gaseous hydrogen to the fuel cell, a dilution box for storing gas exhausted from the fuel cell and generated water, a drainage pipe for directing water to the dilution box and a scupper provided on the drainage pipe and open toward the side of the body. A control valve that is opened or closed at predetermined times is arranged in connection with the drainage pipe.
Claims20
A drainage structure in a fuel cell electric vehicle comprising:
- a fuel cell for generating electric power by reacting hydrogen and oxygen,
- a hydrogen cylinder for supplying gaseous hydrogen to the fuel cell,
- a storage box for storing gas emitted from the fuel cell and generated water,
- a drainage pipe for leading water from the storage box, and
- a scupper provided on the drainage pipe and open toward the side of the vehicle, comprising:
- a control valve for opening or closing at predetermined times, said control valve being arranged for controlling drainage from the drainage pipe,
- wherein the control valve is disposed forwardly of the fuel cell, and the storage box is disposed forwardly of the control valve
- wherein the drainage pipe for leading water from the storage box extends from the control valve and continues rearwardly beneath the fuel cell in a direction that is substantially parallel to a length of the vehicle.
A drainage structure in a fuel cell electric vehicle comprising:
- a fuel cell for generating electric power by reacting hydrogen and oxygen;
- a hydrogen cylinder for supplying gaseous hydrogen to the fuel cell;
- a storage box for storing gas emitted from the fuel cell and generated water;
- a drainage pipe for directing water from the storage box and open toward the side of the vehicle;
- and
- a control valve operatively connected to said drainage pipe for being selectively opened or closed at predetermined times, said control valve being arranged for controlling drainage from the drainage pipe,
- wherein the drainage pipe for leading water from the storage box extends rearwardly from the control valve and continues rearwardly under the fuel cell in a direction that is substantially parallel to a length of the vehicle.
A drainage structure adapted to be used with a fuel cell electric vehicle including a fuel cell for generating electric power by reacting hydrogen and oxygen, a hydrogen cylinder for supplying gaseous hydrogen to the fuel cell, a dilution box for receiving gas emitted from the fuel cell and for storing generated water comprising:
- a drainage pipe operatively connected to said dilution box for discharging water in the dilution box and open toward the side of the vehicle;
- and
- a control valve operatively connected to said drainage pipe for being selectively opened or closed at predetermined times, said control valve being arranged for controlling drainage from the drainage pipe,
- wherein the dilution box is disposed in a position that is forward of the control valve and forward and lower than the fuel cell, and
- wherein the drainage pipe for leading water from the dilution box extends rearwardly from the control valve, and then passes beneath the fuel cell in a lengthwise direction of the vehicle.
