  • Patent number: 9985303
    Abstract: A system and method for determining whether a concentration estimation value of hydrogen gas in an anode sub-system of a fuel cell system is within a predetermined threshold of a valid hydrogen gas concentration, and if not, correcting the estimation value. The method includes providing a hydrogen gas concentration sensor value from a virtual sensor and calculating the hydrogen gas concentration estimation value using a gas concentration estimation model. The method also includes determining if a difference between the estimation value and the sensor value is greater than at least one threshold, and if so, causing an extended bleed event to occur that bleeds an anode exhaust gas to force the estimation value to be closer to the sensor value. The method also includes setting a diagnostic if multiple extended bleeds do not cause the estimation value and the sensor value to converge.
