Abstract
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.
