To provide a liquid hydrogen consuming device for accurately seizing and warning the remaining amount of fuel in a system where liquid fuel and gas fuel exist.
The liquid fuel consuming device to which the liquid fuel is supplied from the outside is constructed so that a gross remaining amount of fuel is computed in accordance with a total value for a remaining amount Q4 of the liquid fuel and a remaining amount Q6 of the gas fuel vaporizing from the liquid fuel. In the system using the gas fuel although the liquid fuel is supplied thereto, the remaining amount of fuel cannot be accurately seized for either the liquid fuel or the gas fuel. In this construction, the gross remaining amount of fuel Q6+Q7 are computed in accordance with the total value for the remaining amount of the liquid fuel and the remaining amount of the gas fuel, and so the gross amount of usable fuel is accurately seized and correct announcement is performed accordingly.
