Abstract
A system and method for controlling hydrogen purging of a fuel cell are provided. The method includes calculating a hydrogen supply amount and estimating a hydrogen consumption amount. An estimated hydrogen concentration is then corrected when a difference between the calculated hydrogen supply amount and the estimated hydrogen use amount is greater than a predetermined threshold value.
