Abstract

There is provided a piping member that is used for a moving body equipped with a fuel cell and that is configured to suppress potential troubles caused by drainage water of the fuel cell. A fuel cell vehicle 1 includes an exhaust pipe 100 that is a piping member configured to discharge drainage water and exhaust gas of a fuel cell 10. The exhaust pipe 100 includes an extended portion 111, a curved portion 112 and an opening end portion 113 and is mounted such that the exhaust pipe 100 opens downward on the rear side of the fuel cell vehicle 1. The exhaust pipe 100 is configured such that an inner wall surface 121 of a wall portion 113 f of the opening end portion 113 located on the front side of the vehicle is inclined from the rear side toward the front side of the fuel cell vehicle 1. to be extended to an opening 101, in the state that the exhaust pipe 100 is mounted to the fuel cell vehicle 1

First claim

1 . A piping member that is mounted to a moving body equipped with a fuel cell and is configured to discharge exhaust gas and drainage water of the fuel cell, the piping member comprising:
an opening end portion that is configured to have an opening and is arranged such that the opening opens downward of the moving body; and a curved pipe portion that is curved toward the opening end portion and is placed on the moving body such that an upstream side thereof is located on a center side in a longitudinal direction or in a lateral direction of the moving body, wherein an inner wall surface on a curve inner circumference of the curved pipe portion out of an inner wall surface of the opening end portion is inclined downward in a direction toward the upstream side of the curved pipe portion.

2 . The piping member according to claim 1 ,
wherein the opening end portion is placed on a rear side of a center in the longitudinal direction of the moving body, the curved pipe portion is placed on the moving body such that the upstream side thereof is located on the center side in the longitudinal direction of the moving body, and the inner wall surface on the curve inner circumference of the curved pipe portion out of the inner wall surface of the opening end portion is inclined downward in a direction from a rear side toward a front side of the moving body.

3 . The piping member according to claim 2 ,
wherein the inner wall surface on the curve inner circumference of the curved pipe portion out of the inner wall surface of the opening end portion is a first inner wall surface located on the front side of the moving body, and the opening end portion has a second inner wall surface that is located on the rear side of the moving body and that is inclined downward in a direction from the front side toward the rear side of the moving body.

4 . The piping member according to claim 2 ,
wherein the inner wall surface on the curve inner circumference of the curved pipe portion out of the inner wall surface of the opening end portion is a first inner wall surface located on the front side of the moving body, and the opening end portion has a second inner wall surface that is located on the rear side of the moving body and that is inclined downward in the direction from the rear side toward the front side of the moving body.

5 . The piping member according to claim 2 ,
wherein the opening end portion has an opening end face in which the opening is formed, and the opening end face is inclined rearward of the moving body in a state that the piping member is mounted to the moving body.

6 . A fuel cell vehicle comprising:
a fuel cell; and a piping member according to claim 1 , wherein the moving body is the fuel cell vehicle.
