Abstract
A fuel cell hydrogen supply fault diagnosis system is provided. The system includes multiple fuel tanks that store hydrogen therein to supply the hydrogen and a fuel tank valve disposed at each of the fuel tanks and configured to be opened or closed to supply or shut off the hydrogen of the fuel tanks. A pressure sensor measures pressure in a fuel supply line that extends from each of the multiple fuel tanks to be integrally connected to a fuel cell stack. A supply amount estimator then estimates a supply amount of hydrogen supplied to the fuel cell stack and a consumption amount estimator estimates a consumption amount of hydrogen consumed in a reaction in the fuel cell stack or discharged therefrom. A fault detector then detects a hydrogen supply state.
