The mobile body includes a driving force generation device which generates a driving force of the mobile body; a power accumulation device and a fuel cell capable of supplying a power to the driving force generation device; and a control device which controls driving of the driving force generation device. The control device prohibits to start driving the driving force generation device by the power supply of the power accumulation device, in a case where there is a possibility of failure in startup of the fuel cell when starting the mobile body. ## Claims ### Claim 1 A mobile body comprising: a driving force generation device which generates a driving force of the mobile body; a power accumulation device configured to supply a power to the driving force generation device; a fuel cell configured to supply a power to the driving force generation device; and a control device which controls driving of the driving force generation device, wherein the control device prohibits to start driving the driving force generation device by the power supply of the power accumulation device, in a case where there is a possibility that startup of the fuel cell fails when starting the mobile body. ### Claim 2 (depends on 1) The mobile body according to claim 1, wherein the control device allows to start driving the driving force generation device after completion of the startup of the fuel cell, in the case where there is the possibility that the startup of the fuel cell fails when starting the mobile body. ### Claim 3 (depends on 1) The mobile body according to claim 1, wherein the control device allows to start driving the driving force generation device simultaneously with completion of the startup of the fuel cell, in the case where there is the possibility that the startup of the fuel cell fails when starting the mobile body. ### Claim 4 (depends on 1) The mobile body according to claim 1, wherein the control device starts driving the driving force generation device by the power supply of the power accumulation device, in a case where the control device judges that the startup of the fuel cell becomes successful when starting the mobile body. ### Claim 5 (depends on 4) The mobile body according to claim 4, wherein the control device switches the power supply to the driving force generation device from the power accumulation device to the fuel cell. ### Claim 6 (depends on 1) The mobile body according to claim 1, wherein the power accumulation device is configured to supply the power to the driving force generation device, before the fuel cell. ### Claim 7 (depends on 1) The mobile body according to claim 1, wherein while prohibiting to start driving the driving force generation device by the power supply of the power accumulation device when starting the mobile body, the control device executes a restoring operation to remove a factor for the failure in the startup of the fuel cell. ### Claim 8 (depends on 7) The mobile body according to claim 7, further comprising an apparatus to execute supply of a gas to the fuel cell and stop of the supply, wherein the control device executes the restoring operation by driving the apparatus so that the gas is supplied to the fuel cell. ### Claim 9 (depends on 8) The mobile body according to claim 8, wherein the control device drives the apparatus by supplying the power to the apparatus from the power accumulation device during the restoring operation. ### Claim 10 (depends on 1) The mobile body according to claim 1, wherein the control device judges based on a situation before the startup of the fuel cell whether or not there is a possibility of the failure in the startup of the fuel cell. ### Claim 11 (depends on 10) The mobile body according to claim 10, wherein the situation before the startup of the fuel cell is an abnormal situation during a previous power generation of the fuel cell. ### Claim 12 (depends on 11) The mobile body according to claim 11, wherein the control device prohibits to start driving the driving force generation device by the power supply of the power accumulation device, in a case where there was an abnormality during the previous power generation of the fuel cell, and the control device starts driving the driving force generation device by the power supply of the power accumulation device, in a case where there was not any abnormality during the previous power generation of the fuel cell. ### Claim 13 (depends on 10) The mobile body according to claim 10, wherein the situation before the startup of the fuel cell is a time for which the fuel cell is left to stand during stop. ### Claim 14 (depends on 13) The mobile body according to claim 13, wherein the control device prohibits to start driving the driving force generation device by the power supply of the power accumulation device, in a case where the leaving time exceeds a threshold value, and the control device starts driving the driving force generation device by the power supply of the power accumulation device, in a case where the leaving time is a threshold value or less. ### Claim 15 (depends on 1) The mobile body according to claim 1, further comprising a timer to measure a time for which the fuel cell is left to stand during stop, wherein the control device determines based on the leaving time measured by the timer whether to prohibit or allow to start driving the driving force generation device by the power supply of the power accumulation device when starting the mobile body. ### Claim 16 (depends on 1) The mobile body according to claim 1, further comprising storage means for storing whether or not there was any abnormality during a previous power generation of the fuel cell, wherein the control device determines, based on the storage of the storage means when starting the mobile body, whether to prohibit or allow to start driving the driving force generation device by the power supply of the power accumulation device. ### Claim 17 (depends on 1) The mobile body according to claim 1, wherein the mobile body is a vehicle.
