<P>PROBLEM TO BE SOLVED: To provide a fuel battery vehicle which highly efficiently recovers regeneration power to a battery without releasing a contactor at the power generation of a fuel battery. <P>SOLUTION: An ECU 24 controls a DC-DC converter 22 to a directly-connected state at the regeneration power generation of a motor 14, lowers oxygen concentration and hydrogen concentration by using a gas supply means, and makes the battery 20 accumulate power while lowering the generation power Pfc (FC current Ifc) of an FC stack 40, thus highly efficiently recovering the regeneration power without releasing the contactor at the power generation of the FC stack 40. <P>COPYRIGHT: (C)2013,JPO&INPIT |
