<P>PROBLEM TO BE SOLVED: To provide a fuel battery system that can accurately measure impedance even after an intermittent operation. <P>SOLUTION: The fuel battery system 10 includes: a fuel battery stack 11; a hydrogen supply system that supplies hydrogen from a hydrogen tank 22; an oxidant gas supply system that supplies air to become an oxidant by an air compressor; an impedance measurement part 13 that measures impedance of the fuel battery; an electric system that includes a DC/DC converter 14 that converts generated power and a secondary battery 15 that stores the power, or the like; and a driving system 50 that drives a vehicle. When an ignition switch is turned off from a state where the power generation is being stopped in the intermittent operation and the power generation is stopped, the impedance measurement part 13 avoids a transient state of a fuel battery cell due to delay of air supply and executes impedance measurement after the air supply becomes. <P>COPYRIGHT: (C)2011,JPO&INPIT |
