<P>PROBLEM TO BE SOLVED: To provide a technology by which a fuel cell and other power supply can be operated appropriately even if there is a gap between a premised supply power when a control part of a motor or an air conditioner controls the fuel cell and the other power supply and the assumed supply power when an operation point of the fuel cell is set, in a power supply device provided with the fuel cell and the other power supply. <P>SOLUTION: In the power supply device provided with the fuel cell and the other power supply connected in parallel to wiring to convey electric power, the target supply power P<SB>perm</SB>of the fuel cell and the first target supply power P<SB>1BAT</SB>of the other power supply are firstly set. A power converter installed at the other supply power is regulated so that the supply power of the other power supply is increased from the first target supply power P<SB>1BAT</SB>in the case the actual supply power of the fuel cell is larger than the target supply power P<SB>perm</SB>of the fuel cell, and so that the supply power of the other power supply is decreased when it is small. Then, the actual supply power of the fuel cell is controlled so as to be within a prescribed range near the target supply power P<SB>perm</SB>. <P>COPYRIGHT: (C)2004,JPO |
