<P>PROBLEM TO BE SOLVED: To provide a power supply system for a fuel cell vehicle which gives a proper fuel consumption without increasing the size of a DC-DC converter. <P>SOLUTION: The power supply system for the fuel cell vehicle includes a fuel battery 20, a chargeable/dischargeable storage means 30, the DC-DC converter 40 having a first terminal 41 connected in series with the storage means 30 and a second terminal 42 connected in series with the fuel battery 30 and capable of regulating the voltage of the second terminal, a regenerated power recovering means 61 connected in parallel with the fuel battery 20 between the fuel battery 20 and the DC-DC converter 40, and regenerated power consuming means 71, 81 connected in parallel with the regenerated power recovering means 61 between the fuel battery 20 and the DC-DC converter 40 and capable of consuming the regenerated power recovered by the regenerated power recovering means 61. When the regenerated power is recovered by the regenerated power recovering means 61, the voltage of the second terminal 42 is regulated to a predetermined voltage or higher. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
