To provide a cooling device for fuel cell electric vehicle capable of facilitating installation of multiple radiators in a little installation space and efficiently cooling a fuel cell and a drive motor.
This cooling device 26 for fuel cell electric vehicle includes the fuel cell, the drive motor generating traction power, a first radiator 31 for cooling the fuel cell, and a second radiator 41 for cooling the drive motor. Ventilation opening sizes W1, W2 and H1, H2 are set to approximately the same respectively to each other, and a heat radiation space A2 of the second radiator is set smaller compared to a heat radiation space A1 of the first radiator. Then, the second radiator is arranged at the front portion of the fuel cell electric vehicle, and the first radiator is adjacently arranged at the backward of the second radiator with surrounding areas between the first and second radiators being sealed with sealing members. A radiator air-cooling fun shared by the first and second radiator is installed at the back of the first radiator.
