ABSTRACT:
A gas feed device for detecting trouble in a gas pressure sensor fitted to the gas feed device. The presence of trouble in pressure sensors is determined according to whether or not gas pressure values detected by the pressure sensors fitted to branch pipes is within an allowable range when stop valves fitted to the branch pipes connected to the access ports of hydrogen absorbing alloy tanks are fully opened from their fully closed state. When the gas feed device is mounted on a vehicle, no special operation is required for trouble detection because the trouble in the pressure sensors can be detected by fully opening the fully closed stop valves when the vehicle is started and normally the trouble can be judged by the mounted equipment.
