Abstract
Provided is an apparatus and method for diagnosing a fault of a fuel cell stack based on measurement of a stack current. The apparatus includes an alternating-current (AC) generation circuit configured to apply an AC to a fuel cell stack driven by a basic operating current (direct-current: DC), a current measurement circuit configured to measure a current of the fuel cell stack caused by the DC applied to the fuel cell stack, and a Micom configured to diagnose a fault of the fuel cell stack on the basis of a current measurement result of the current measurement circuit.
Claims9
An apparatus for diagnosing a fault of a fuel cell stack based on measurement of a stack current, the apparatus comprising:
- an alternating-current (AC) generation circuit configured to apply an AC to a fuel cell stack driven by a basic operating current (direct-current:
- DC);
- a current measurement circuit configured to measure a current of the fuel cell stack caused by the DC applied to the fuel cell stack;
- and
- a Micom configured to diagnose a fault of the fuel cell stack on the basis of a current measurement result of the current measurement circuit.
A method for diagnosing a fault a fuel cell stack based on measurement of a stack current, the method comprising:
- applying, by an AC generation circuit, an AC to a fuel cell stack driven by a basic operating current (DC);
- measuring, by an AC generation circuit, a current of the fuel cell stack caused by the AC applied to the fuel cell stack;
- and
- diagnosing, by a Micom, the fault of the fuel cell stack on the basis of a current measured result of the current measurement circuit.
