FUEL CELL COOLING SYSTEM FOR VEHICLE AND FUEL CELL-POWERED VEHICLE

摘要

The grill shutter is disposed between the front grill and the air intake duct. The grill shutter is capable of opening or closing shutter members and regulating positions of the shutter members when being opened. When a maximum supplied flow rate of air provided by the wind during running is greater than a flow rate of air required for the hydrogen fuel battery, the required flow rate of air is established only by opening/closing control of the shutter members through a grill shutter opening instruction. If this is not the case, the grill shutter members are opened fully through the grill shutter opening instruction to maximize the volume of the wind during running taken in from the front grille. Additionally, a shortfall in the required flow rate of air for the hydrogen fuel battery is compensated for by actuating the blower through a blower speed instruction.

主权项

1. A fuel cell cooling system for a vehicle comprising:
a first air inlet provided in a front portion of a vehicle; an air supply path which supplies air, as taken in from said first air inlet, to a fuel cell which supplies electric power to a driving motor; a regulating member which is provided in said air supply path and regulates an amount of air to be supplied from the air supply path to said fuel cell; a blower which provides an air flow to said fuel cell; and a control portion which controls said regulating member and said blower to regulate an amount of air supplied from the air supply path and the blower to the fuel cell.
