Abstract
A fuel cell vehicle is provided with a fuel cell stack and a vehicle body frame for mounting the fuel cell stack in a front box. The fuel cell stack and a frame member have portions overlapping with each other in a vehicle width direction in a plan view of the vehicle. A vehicle-forward end portion of the fuel cell stack is positioned closer to the rear of the vehicle than a vehicle-forward end portion of the frame member. A vehicle-rearward end portion of the fuel cell stack is positioned closer to the front of the vehicle than a vehicle-rearward end portion of the frame member.
Claims9
A fuel cell vehicle comprising:
- a fuel cell stack formed by stacking a plurality of fuel cells, the fuel cells each generating electrical energy by electrochemical reactions of a fuel gas and an oxygen-containing gas;
- a front box;
- a vehicle frame configured to mount the fuel cell stack in the front box;
- a radiator provided on a front side of the fuel cell stack in a vehicle front-rear direction, a coolant used for cooling the fuel cells passing through the radiator;
- and
- a fan motor provided on a rear side of the radiator and configured to drive a radiator fan to send air to the radiator;
- and
- an impact relaxing mechanism configured to relax an impact applied from an outside, a length of the impact relaxing mechanism being greater than a length of the fuel cell stack in the vehicle front-rear direction, the impact relaxing mechanism being attached to the vehicle frame for placement of the fuel cell stack,
- wherein the fuel cell stack and the impact relaxing mechanism have an overlapped portion in which the fuel cell stack and the impact relaxing mechanism are overlapped with each other in a vehicle width direction in a plan view of the fuel cell vehicle;
- a front end of the fuel cell stack in the vehicle front-rear direction is positioned rearward of a front end of the impact relaxing mechanism in the vehicle front-rear direction;
- a rear end of the fuel cell stack in the vehicle front-rear direction is positioned forward of a rear end of the impact relaxing mechanism in the vehicle front-rear direction;
- and
- a distance between the front end of the fuel cell stack in the vehicle front-rear direction and the front end of the impact relaxing mechanism in the vehicle front-rear direction is greater than a dimension of the fan motor in the vehicle front-rear direction.
