<P>PROBLEM TO BE SOLVED: To provide a fuel cell power feeding system suitable for a small equipment such as a portable information device. <P>SOLUTION: The fuel cell power feeding system 1 is structured by connecting a fuel cell 2 and an DC-DC converter 3 in series, connecting the fuel cell 2 and a direct current energy storage device 9 in parallel at an output side of the DC-DC converter 3, and connecting an ammeter 4 and a voltmeter 5 between the fuel cell 2 and the DC-DC converter 3. Then, an output power of the fuel cell 2 is controlled by the DC-DC converter 3 so as to be not less than a preset lowest output voltage value of the fuel cell 2, and an output current detected by the ammeter 4 is controlled by the DC-DC converter 3 so as to be not more than a preset stable output current value of the fuel cell 2. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
