In a hydrogen tank, discharge of a hydrogen gas may cause lowering of the temperature to a value at which it is assumed that disconnection has occurred in a thermistor. A temperature detection system for the hydrogen tank estimates the possibility that the temperature of the hydrogen tank is below this temperature value, according to the ambient temperature and the internal pressure. Only when there is no possibility that the temperature is below the value, disconnection is judged to have occurred.
