Patent ID: 8435688

Claim:
A cooling apparatus of a fuel cell vehicle, the cooling apparatus comprising: a fuel cell; a hydrogen supply source that supplies hydrogen to the fuel cell through a hydrogen supply path; a supercharger that supplies air to the fuel cell; a motor as a driving source of the fuel cell vehicle; and a motor driver which drives the motor; a heat sink mounted adjacent to the motor driver; a first air exhaust path extending between the fuel cell and the heat sink so that exhaust entering the first air exhaust path from the fuel cell cools the motor driver and is discharged to an outside of the heat sink; a battery that supplies electric power to the motor; a second air exhaust path with a first end branching from a central portion of the first air exhaust path and a second end adjacent to the battery; a temperature detector that detects temperature of the battery; a valve provided in a middle of the second air exhaust path; and a controller programmed to open the valve in the second air exhaust path when the temperature of the battery detected by the temperature detector is higher than a first temperature so that a flow rate of the exhaust flowing from the fuel cell to the battery becomes larger.
