Fuel cell motorcycle

Abstract

A layout for an exhaust pipe which also serves as a drainage pipe which prevents splashing of water generated in a fuel cell toward a passenger or splashing toward a tire. Humid excessive gas supplied from a fuel cell (25) is diluted in a dilution box (32) by off-gas discharged from the fuel cell (25) and is used for humidifying air in the humidifier (30). An exhaust pipe is connected to the dilution box (32), and diluted hydrogen gas is discharged via the exhaust pipe (38). Vapor mixed in hydrogen gas is condensed in the exhaust pipe (38) and turned into water, which is drained through the exhaust pipe (38) that extends rearwardly of a vehicle body through the interior of a power unit (19) . A discharge port of the exhaust pipe (38) (which is also a drainage port for water generated in the fuel cell) is positioned at the widthwise center of the vehicle body.

Description

technical field [0001] The present invention relates to a fuel cell motorcycle, in particular to a fuel cell motorcycle having a drainage device for discharging water generated in the fuel cell to the outside of the vehicle body. Background technique [0002] From the viewpoint of environmental protection and securing of energy resources to replace fossil fuels, fuel cell motorcycles that use electric energy generated by the fuel cells as a power source for driving electric motors are being developed focusing on fuel cells. When the fuel cell generates electricity, hydrogen ions and electrons are released from hydrogen as fuel, and the hydrogen ions combine with oxygen and the electrons released from the hydrogen at the cathode to produce water. JP-A-2001-313056 discloses a drain device for a fuel cell. In this drainage device, the drain port is arranged on the side of the vehicle body, and the water is discharged to the side of the vehicle body so as not to discharge water...

AI Technical Summary

Problems solved by technology

[0004] In the drain device described in Patent Document 1, since the drain port is arranged on the side of the vehicle body, the discharged water may splash on the feet of the driver and passengers when they are supported. To avoid these problems, the drain port It becomes difficult to freely design such as pedals for the passenger

In addition, when the drain port is arranged on the side of the vehicle body, the width of the vehicle increases, and the appearance of the car may be affected by the drain port exposed on the side of the vehicle body.
