Abstract

A diagnostic system and method for a fuel cell stack that diagnoses the state and/or failure of the fuel cell stack. More specifically, the diagnostic control analyzer diagnoses and analyzes the state of the fuel cell stack by measuring the voltage and the current received from the fuel cell stack. To do this, an AC signal generator cogenerates a diagnostic AC signal according to the control upon receiving a control command form the analyzer, and an AC component driving element is then driven upon receiving the AC signal that is output from the AC signal generator in order to include a diagnostic AC component within the current of the fuel cell stack. In particular, the diagnostic control analyzer diagnoses the fuel cell stack based on a voltage and a current received from the fuel cell stack that includes the AC component via a load.
