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 for preventing deterioration of a fuel cell caused by resistance detection of an electrolyte membrane and determining start of the resistance detection of the electrolyte membrane on the basis of an operation state of the system.

SOLUTION: Resistance detection of an electrolyte membrane is performed on the basis of time series transition of an operation state detecting an operation state of a system, current taken out of a fuel cell stack 1 and voltage in the fuel cell stack. Start of the resistance detection of the electrolyte membrane is determined on the basis of the operation state of the system.
