Vehicle
A vehicle includes: a front room disposed at a front portion of the vehicle in the vehicle in a vehicle-longitudinal direction; a fuel cell stack disposed in the front room, the fuel cell stack including multiple cells stacked in the vehicle-longitudinal direction; and a buffer member disposed in front of the fuel cell stack in the vehicle-longitudinal direction.
1. A vehicle comprising:
a front room disposed at a front portion of the vehicle in the vehicle in a vehicle-longitudinal direction;
a fuel cell stack disposed in the front room, the fuel cell stack comprising multiple cells stacked in the vehicle-longitudinal direction inside of a fuel cell case; and
a buffer member disposed in front of the fuel cell case and a stack frame in the vehicle-longitudinal direction;
wherein the stack frame supports the fuel cell stack from a bottom of the fuel cell stack, and the buffer member is fixed to a front end of the stack frame and supported by the stack frame.
2. The vehicle according to claim 1 , wherein
the buffer member is configured to reduce an input load into the fuel cell stack at a front collision time of the vehicle at a predetermined rating speed to be smaller than a durable load of the fuel cell stack at the front collision time of the vehicle at the predetermined rating speed.
3. The vehicle according to claim 2 , wherein
the predetermined rating speed is 56 km/h.
4. The vehicle according to claim 1 , further comprising
a mount fixing the stack frame to the vehicle.
5. The vehicle according to claim 1 , wherein
the vehicle is a fuel cell vehicle.
6. The vehicle according to claim 1 , wherein the buffer member is selected from the group consisting of a crush box, a container containing impact absorbing gel, a rubber plate, and a spring.
7. The vehicle according to claim 1 , further comprising a radiator disposed at a frontward position in the front room in the vehicle longitudinal direction, and wherein the buffer is disposed between the radiator and the fuel cell case.
8. A vehicle comprising:
a front room disposed at a front portion of the vehicle in the vehicle in a vehicle-longitudinal direction;
a fuel cell stack disposed in the front room, the fuel cell stack comprising multiple cells stacked in the vehicle-longitudinal direction inside of a fuel cell case; and
a buffer member disposed in front of the fuel cell case and a stack frame in the vehicle-longitudinal direction;
wherein the buffer member is fixed to a front end of the stack frame and supported by the stack frame.
9. The vehicle according to claim 8 , wherein
the buffer member is configured to reduce an input load into the fuel cell stack at a front collision time of the vehicle at a predetermined rating speed to be smaller than a durable load of the fuel cell stack at the front collision time of the vehicle at the predetermined rating speed.
10. The vehicle according to claim 9 , wherein
the predetermined rating speed is 56 km/h.
11. The vehicle according to claim 8 , wherein
the vehicle is a fuel cell vehicle.
12. The vehicle according to claim 8 , wherein the buffer member is selected from the group consisting of a crush box, a container containing impact absorbing gel, a rubber plate, and a spring.
