<P>PROBLEM TO BE SOLVED: To provide a fuel cell vehicle which can reduce the startup time of a fuel cell at low temperature time. <P>SOLUTION: In the fuel cell vehicle, stepwise warm-up control is executed in which the amount of heat radiation of a fuel cell stack is controlled stepwise at the startup of the fuel cell stack. In the stepwise warm-up control, when an FC power generation possible voltage Vfcp which is determined according to the temperature of the fuel cell stack rises to or above an auxiliary machine operable minimum voltage Vamin, or when a temperature Tw of the fuel cell stack rises to or above a first temperature corresponding to the auxiliary machine operable minimum voltage Vamin, an FC voltage Vfc is set to the auxiliary machine operable minimum voltage Vamin before the auxiliary machine is allowed to operate. Thereafter, when the FC power generation possible voltage Vfcp rises to or above a drive force generation minimum voltage Vmotmin1, or when the temperature Tw of the fuel cell stack rises to or above a second temperature corresponding to the drive force generation minimum voltage Vmotmin1, the FC voltage Vfc is set to the drive force generation minimum voltage Vmotmin1 before a drive force generation source is allowed to operate. <P>COPYRIGHT: (C)2013,JPO&INPIT |
