<P>PROBLEM TO BE SOLVED: To provide a fuel cell system in which discharge of a fuel cell is controlled in a simple circuit composition without a cost increase. <P>SOLUTION: In switching elements 38, 42(k) in each of discharging circuits 33(1)-33(n) connected with cell groups 23(1)-23(n), divided voltages generated from output voltages of the corresponding cell groups 23(1)-23(n) are inputted as ON/OFF signals. As a result, a discharge control of the fuel cell can be conducted in a simple composition without using an expensive insulation element such as a photo-coupler or the like for insulating electrically between input ports of transistor elements 38, 42(k) and output ports of controlling signals. <P>COPYRIGHT: (C)2009,JPO&INPIT |
