Fuel cell vehicle

1. A fuel cell vehicle including an exhaust device configured to discharge an exhaust gas from a stack case containing a fuel cell stack,

wherein the exhaust device comprises:

an exhaust port unit provided in a fender of the fuel cell vehicle; and

an exhaust duct configured to couple the stack case and the exhaust port unit together, and

wherein the exhaust port unit comprises:

a hollow exhaust port body having an outer opening opened to outside of the fuel cell vehicle; and

a foreign matter entry suppression part in form of a plate provided in an inner hole of the exhaust port body in a manner that the foreign matter entry suppression part covers at least part of the outer opening,

wherein the exhaust port body includes a front wall and a rear wall and extends between the front wall and the rear wall in a front/rear direction of the fuel cell vehicle; and

the foreign matter entry suppression part comprises:

a first plate in contact with the front wall and extending from the front wall in the front/rear direction of the fuel cell vehicle, wherein a distal end of the first plate is distanced from the rear wall;

a second plate in contact with the rear wall and extending from the rear wall in the front/rear direction of the fuel cell vehicle, wherein a distal end of the second plate is distanced from the front wall, and

a gap between the first plate and the second plate formed from an offset of the first plate and the second plate in a left/right direction of the fuel cell vehicle, wherein the exhaust duct is in fluid communication with the outer opening via the gap.

2. The fuel cell vehicle according to claim 1 , wherein the first plate and the second plate are overlapped with each other in the left/right direction of the fuel cell vehicle.

3. The fuel cell vehicle according to claim 1 , wherein a drain hole is formed at a bottom of the exhaust port body.

4. The fuel cell vehicle according to claim 3 , wherein the exhaust device comprises a drain pipe, and one end of the drain pipe is connected to the drain hole and another end of the drain pipe is positioned on a vehicle rear side of a front wheel of the fuel cell vehicle.

5. The fuel cell vehicle according to claim 3 , wherein the drain hole is formed at one end of the exhaust port body; and

the exhaust duct is connected to another end of the exhaust port body.

6. The fuel cell vehicle according to claim 3 , wherein the exhaust port body includes an inner wall connecting the front wall to the rear wall,

the first plate is fixed to the exhaust port body by a bolt, which is tightened to a boss protruding from the inner wall toward the outer opening, and

the bolt and the boss are offset from the drain hole in the longitudinal direction of the exhaust port body.

7. The fuel cell vehicle according to claim 1 , wherein a filter case containing a filter is provided in the exhaust duct.

8. The fuel cell vehicle according to claim 7 , wherein an intermediate drain hole is formed at a bottom of the filter case.

9. The fuel cell vehicle according to claim 8 , wherein the exhaust device comprises an intermediate drain pipe, and one end of the intermediate drain pipe is connected to the intermediate drain hole and another end of the intermediate drain pipe is positioned on a vehicle front side of a front wheel of the fuel cell vehicle.

10. The fuel cell vehicle according to claim 7 , wherein the exhaust duct comprises a pipe configured to couple the filter case and the exhaust port unit; and

an outlet port of the filter case connected to one end of the pipe is positioned vertically below an inlet port of the exhaust port unit where another end of the pipe is connected; and

the pipe is inclined vertically downward from the inlet port toward the outlet port.

11. The fuel cell vehicle according to claim 7 , wherein the exhaust duct includes a tube connecting the filter case to the exhaust port,

the exhaust port body includes an inner wall connecting the front wall to the rear wall,

the second plate is fixed to the exhaust port body by a bolt, which is tightened to a boss protruding from the inner wall toward the outer opening.

12. The fuel cell vehicle according to claim 1 , wherein the exhaust port unit includes a cover provided in the exhaust port body in a manner that the cover covers the outer opening from the outside, and a plurality of through holes as passages of the exhaust gas are formed in the cover.

13. The fuel cell vehicle according to claim 1 , wherein a plurality of the first plates are spaced from, and face each other in the left/right direction of the fuel cell vehicle.

14. The fuel cell vehicle according to claim 1 , wherein an expansion is provided at the other end of the exhaust port body in the front/rear direction of the fuel cell vehicle, and the expansion is expanded opposite to the first plate, from a position shifted from the second plate in the left/right direction of the fuel cell vehicle in which the outer opening is oriented; and

an inclined surface is formed in a surface of the expansion oriented toward the outer opening, and the inclined surface is inclined in the left/right direction of the fuel cell vehicle in which the outer opening is oriented and the expansion is expanded.

15. The fuel cell vehicle according to claim 1 , wherein the first plate and the second plate are not overlapped with each other in the left/right direction of the fuel cell vehicle.
