<P>PROBLEM TO BE SOLVED: To secure power generation stability of a fuel cell. <P>SOLUTION: A fuel cell system comprises: a fuel cell 1, to which hydrogen and air are supplied and which generates power; exhaust processing means for exhausting impurities generated in the fuel cell 1 by supplying exhausting gas (hydrogen or air); an ammeter 64 for measuring a current value outputted from the fuel cell 1; a voltmeter 65 for measuring a voltage value outputted from the fuel cell 1; and a control device 50 for controlling the exhaust processing means. The control device 50 finds a current deterioration rate of the fuel cell 1 by comparing a current value and a voltage value measured by the ammeter 64 and the voltmeter 65 during generating the power of the fuel cell 1 with a deterioration rate determining map defined by the current value and the voltage value in advance, and controls an exhaust processing related amount of the exhaust processing means to be larger than when the cell is not deteriorated as the current deterioration rate is larger. <P>COPYRIGHT: (C)2012,JPO&INPIT |
