Title:

FUEL CELL AUTOMOBILE AND RELEASE TUBE INSTALLATION STRUCTURE FOR GAS FUEL AUTOMOBILE

Document Type and Number:

WIPO Patent Application WO/2006/059599

Kind Code:

A1

Abstract:

A release opening (52) of a release tube (51) for a relief valve (50) is provided at a position near a discharge opening (170) of a fuel cell box (39), the position being in a space between a subframe (22) and the fuel cell box (39). An introduction opening (130) is formed in a front wall (120) of the fuel cell box (39), and airflow can be supplied into the fuel cell box (39) by a fan (180). Outside air supplied to the fuel cell box (39) passes a fuel cell (38) as a ventilation flow to cool the fuel cell (38) while ventilating. Discharge air is discharged rearward from the discharge opening (170) of a discharge duct (160). The release tube (51) and the release opening (52) are heated by the discharge air, so that blocking of the release opening (52) by snow or freezing can be removed by the heating.
