METHOD AND APPARATUS FOR DIAGNOSING FAULT OF FUEL CELL STACK BASED ON MEASUREMENT OF STACK CURRENT |
| 摘要 |
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. |
