<P>PROBLEM TO BE SOLVED: To provide a fuel cell system capable of a stable operation even in the case thin separators are used with a large resistance in a plane direction. <P>SOLUTION: The system is provided with a fuel battery 1 laminating unit fuel cells equipped with an electrolyte film 2, a pair of electrodes 3, 4 pinching the electrolyte film 2, and separators 5 having flow channels for supplying fuel gas to one of the electrodes 3 and supplying oxidant gas to the other electrode 4, a resistance measuring instrument 7 detecting a dry/wet state of the electrolyte film 2, a dry state judgment means 15 judging whether the electrolyte film 2 is an a dry state or not based on information detected by the resistance measuring instrument 7, and deterioration evading means 8, 9, 10 short-circuiting the separators 5 pinching the electrolyte film 2 judged to be in a dry state, in the case the electrolyte film 2 is judged to be in a dry state by the dry state judgment means 15. <P>COPYRIGHT: (C)2007,JPO&INPIT |
