<P>PROBLEM TO BE SOLVED: To economically and simply detect electrical short-circuit of a fuel cell. <P>SOLUTION: A short-circuit estimating cell the cell voltage Vn of which drops to a level lower than a water clogging determining value Vf is specified, and when the cell voltage Vn of this short-circuit estimating cell rises after it drops, and the cell voltage Vn of an adjoining cell adjacent to the short-circuit estimating cell is larger than an average cell voltage, generation of electrical short-circuit is determined. <P>COPYRIGHT: (C)2009,JPO&INPIT |
