A fuel cell stack is located in a front room of a fuel cell vehicle. The fuel cell stack is connected to a fuel gas guide passage extending to a widthwise central part in front of a windshield of the fuel cell vehicle. When a fuel gas is leaked from the fuel cell stack, the fuel gas is guided by the fuel gas guide passage and discharged from a discharge outlet formed in the widthwise central part through an opening formed in a hollow cover to the outside. The fuel gas guide passage is connected to a filter case in a fuel gas detector for fuel cells.

Fuel cell vehicle and fuel gas detector for fuel cell

An exhaust device of a fuel cell vehicle includes an exhaust port unit provided in a fender of the fuel cell vehicle, and an exhaust duct coupling a stack case and the exhaust port unit. The exhaust port unit includes a hollow exhaust port body having an outer opening, and a foreign matter entry suppression part in the 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.

Fuel cell vehicle

A stack case includes a lower surface and at least one through hole. The lower surface is at a bottom of the stack case in a vehicle height direction of the vehicle. The at least one through hole opens to an inside of the stack case. An outer opening opens to an outside of a vehicle. The at least one vent pipe has one end and another end opposite to the one end along a length of the at least one vent pipe. The one end is connected to the at least one through hole provided in the stack case. The another end is connected to the outer opening in the vehicle body. The drain hole is provided in the lower surface of the stack case to be open to an inside of a motor compartment. The drain hole is located below the outer opening in the vehicle height direction.

An exhaust apparatus for discharging exhaust gas from a stack case housing a fuel cell stack includes an exhaust duct in communication with an exhaust port of a vehicle and the stack case and a filter case provided to the exhaust duct and housing a filter. A curved exhaust flow path in which a flow path curves at a plurality of locations is provided in the filter case.
