Abstract
A fuel cell failure diagnostic apparatus is provided. The apparatus includes a water-level sensor that senses a water-level of water generated at an anode side of a fuel cell stack and stored in a water trap and a drain valve for the drain control of the generated water. A drain valve position sensor senses a position of the drain valve. A controller detects a failure situation by performing failure diagnosis based on the sensing information generated from the water-level sensor and the drain valve position sensor, and performs a corresponding control depending upon the failure situation.
