Title: METHOD AND APPARATUS FOR DIAGNOSING STATE OF FUEL CELL SYSTEM
Abstract:
Disclosed is a method for diagnosing the state of a fuel cell system. The method for diagnosing the state of the fuel cell system according to one embodiment of the present invention includes the steps of: calculating a duty rate and an average output current based on real-time driving data for preset driving time when a fuel cell vehicle drives; drawing a reference current value based on the calculated duty rate and average output current; and diagnosing the state of the fuel cell system by selecting a state graph corresponding to the drawn reference current value among the state graphs which are different according to the reference current value.
