<P>PROBLEM TO BE SOLVED: To achieve reduction of size and high efficiency without varying a supply voltage to a low voltage load. <P>SOLUTION: A current collection plate 4 is inserted between fuel cell stacks 2, and part of generated power of the fuel cell stack 2 generated between a current collection plate 3a arranged at the end of the fuel cell stack 2 and the current collection plate 4 is taken out therefrom. The power taken out is supplied to a load V2 operating with low voltage. By the above, a transformer for converting the power taken out from a whole of the fuel cell stacks into low voltage is disused, and system efficiency can be heightened. Further, when the load V2 is in need of a certain voltage, the voltage supplied to the load V2 can be stabilized by stabilizing the output current of the fuel cell 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
