FUEL CELL SYSTEM, FUEL CELL VEHICLE, AND RESISTANCE DETECTING METHOD OF ELECTROLYTE MEMBRANE

摘要

PROBLEM TO BE SOLVED: To provide a fuel cell system preventing deterioration of a fuel cell caused by resistance detection of an electrolyte membrane and determining start of resistance detection of the electrolyte membrane based on the operation state of the system.

SOLUTION: The resistance detection of the electrolyte membrane is performed based on time series transition of an operation state detecting the operation state of the system; current taken out of a fuel cell stack; and voltage in the fuel cell stack, and start of resistance detection of the electrolyte membrane is judged based on the operation state of the system.
