<P>PROBLEM TO BE SOLVED: To provide a humidity judgement device of a fuel cell in which a humidity deficient unit cell and a humidity excessive unit cell which cause a voltage drop can be judged accurately irrespective of a lamination position of the unit cell. <P>SOLUTION: The humidification judgement device is provided with a voltage sensor 22 to measure a voltage of a battery unit 30 composing a fuel cell 1 and a humidification judgement part 21 to make a judgement of a humidification of the fuel cell 1, and in case there is any unit battery having a lower voltage than a predetermined voltage, the humidification judgement part 21 make the judgement that the fuel cell 1 is deficient of humidification if a voltage of a battery unit near the battery unit is lower than a humidification excessive judgement voltage and that the fuel cell 1 is excessive of humidification if a voltage a battery unit near the battery unit is higher than the humidification excessive judgement voltage. <P>COPYRIGHT: (C)2008,JPO&INPIT |
