Patent ID: 8014949

Claim:
A mobile body, comprising: an energy generator configured to generate energy from a supplied fuel gas; a gas leakage detecting unit configured to detect leakage of the fuel gas out of the energy generator; a control unit configured to control power output of the energy generator; an information obtaining unit configured to obtain environmental information on an environment around the mobile body from a predetermined information source; a power-control-manner determining unit configured to determine a power-control manner, in which the control unit controls the power output of the energy generator, based on the environmental information on the environment around the mobile body when leakage of the fuel gas is detected by the gas leakage detecting unit; the power-control-manner determining unit includes a unit configured to determine a power-control-prohibited place based on the environmental information, and the power-control-manner determining unit is configured to cause the control unit to allow the energy generator to keep running if leakage of the fuel gas is detected by the gas leakage detecting unit when the mobile body is running in the power-control-prohibited place, thereby allowing the mobile body to be powered by the energy generator until the mobile body exits the power-control-prohibited place.
