PROBLEM TO BE SOLVED: To provide a fuel battery system for detecting dryness of an electrolyte film based on the impedance on fuel cells capable of preventing erroneous detection.SOLUTION: When the coolant temperature is lower than a predetermined temperature (NO in step S310), the fuel battery system does not execute dry detection based on real number part of the impedance (step S320,S330,S340). With this, erroneous detection which occurs when the coolant temperature is lower than the predetermined temperature is prevented.SELECTED DRAWING: Figure 3 |
