FUEL CELL APPARATUS FOR VEHICLES

摘要

A vehicle fuel cell apparatus includes a fuel cell stack configured to take in air as a reaction gas and a coolant through an air intake aperture area, and discharge temperature-raised air through air discharging aperture areas. An air suction duct, air discharge ducts, and air discharge fans take in air to the air suction duct. The air discharge ducts have air discharge ports in the vicinity of the air suction duct. The air suction duct is formed with first air intake ports opening at its upstream end portion, and second air intake ports opening at locations nearer to the air discharge ports of the air discharge ducts than the first air intake ports. The second air intake ports are provided with shutters. The arrangement provides a vehicle fuel cell apparatus having enhanced operability in situations involving low-temperature outside air, and allows for enhanced mountability to vehicles.

主权项

1. A vehicle fuel cell apparatus including a fuel cell stack disposed in a space enclosed by vehicle body panels, and configured to take in air as a reaction gas and a coolant through an air in-taking aperture area to an inside thereof, and discharge temperature-raised air through an air discharging aperture area to an outside thereof, an air suction duct connected to the air intake aperture area, an air discharge duct connected to the air discharging aperture area, and a fan configured to take in air to the air suction duct, the vehicle fuel cell apparatus comprising:
the air discharge duct having an air discharge port thereof disposed in a vicinity of the air suction duct; the air suction duct being formed with a first air intake port set opening at an upstream end portion of the air suction duct, and a second air intake port set opening at a location set nearer to the air discharge port than the first air intake port set; and a shutter set provided at the second air intake port set to open or close the second air intake port set.
