<P>PROBLEM TO BE SOLVED: To supply electric power to a load stably with a simple and cost-effective structure, even if the electric power required by the load fluctuates. <P>SOLUTION: A fuel cell power supply 10 is structured with a voltage regulating device 13, which regulates a voltage outputted from a fuel cell 11 that generates electric power by receiving a reaction gas, and a capacitor module 14, which comprises a plurality of capacitor cells, connected in parallel. In supplying electric power to the load 20, a fuel cell control device 31 controls the capacitor module 14 by switching the connection modes of the capacitor cells between series and parallel connections according to the change of the output voltage required by the load 20. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
