Abstract
Disclosed is a technique of diagnosing a state of a fuel cell system. The technique includes configuring a processor to calculate a duty ratio and an average output current, based on real-time driving data for a preset driving period, during operation of a fuel cell vehicle; obtain a reference current value from the calculated duty ratio and the calculated average output current; and determine a state of a fuel cell system by choosing a state graph corresponding to the obtained reference current value among a plurality of state graphs which vary depending on each reference current value.
