<P>PROBLEM TO BE SOLVED: To provide a cell state monitoring device for a fuel cell stack capable of individually monitoring a state of each cell of a fuel cell constituting the fuel cell stack in spite of simple constitution. <P>SOLUTION: A local controller 32 is furnished every cell 2 of the fuel cell of the fuel cell stack 1, each local controller 32 is signal transferred so as to electrically insulate in one direction, a state signal of the cell 2 of the fuel cell is successively transferred to a main controller 4, and the potential difference between the cells 2 of each fuel cell is overcome while wiring and circuit constitution are simplified. <P>COPYRIGHT: (C)2003,JPO |
