<P>PROBLEM TO BE SOLVED: To provide a power feeding system of a fuel cell for keeping correspondences to load variations, and in addition, protecting a power storage means from over discharge. <P>SOLUTION: The system comprises two power storage means 10, 12 connected to a fuel cell 1 and a load 4 in an openable/closable manner, and a circuit opening/closing means 13-16 for enabling switching a state that one power storage means 10 or 12 is connected to the fuel cell 1 and not connected to the load 4 and also other power storage means 10 or 12 is not connected to the fuel cell 1 and connected to the load 4 to a state that, on the contrary, one power storage means 10 or 12 is not connected to the fuel cell 1 and connected to the load 4 and also other power storage means 10 or 12 is connected to the fuel cell 1 and not connected to the load 4. Therefore, the power generated by the fuel cell 1 is exclusively fed for the charge of the power storage means 10, 12, the burden on the load variations of the fuel cell 1 can be reduced, the power feeding to the load 4 is performed from the power storage means 10, 12, and the system can correspond to the load variations within the ability ranges of the power storage means 10, 12. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
