<P>PROBLEM TO BE SOLVED: To provide a fuel battery system which enables a low-voltage operation of a fuel battery and achieves a reduction in weight and cost. <P>SOLUTION: A DC/DC converter 51 has a function of raising a dc voltage inputted from a fuel battery 2 to output the dc voltage to a load 53 and a function of raising/lowering a dc voltage inputted from a battery 52 to output the dc voltage to the load 53 while raising/lowering a dc voltage inputted from the load 53 to output the dc voltage to the battery 52. The DC/DC converter 51 includes one inductor L1 and a plurality of FETs F1 to F7. A control unit controls turning on and off of the FETs F1, F2, and F3 to switch the destination of connection on the power supply side of the inductor L1 to the fuel battery 2 or the battery 52. <P>COPYRIGHT: (C)2010,JPO&INPIT |
