A ventilation fan (180) is attached to a chassis (100) and exhausts air inside the chassis (100) to the outside of the chassis (100). A first detection unit (200) monitors the operation of the ventilation fan (180). When the detection result by the first detection unit (200) indicates that the rotation speed of the ventilation fan (180) has become a reference value or less, a relay circuit unit (210) outputs a signal to a shut-off valve (110), said signal allowing the shut-off valve (110) to perform a closing operation. The shut-off valve (110) is provided in a pipe of a fuel gas supply unit installed at the entrance of a fuel cell
main body and, upon the reception of the signal, shuts off the supply of a fuel gas to a fuel cell
