Abstract
A method for estimating a hydrogen concentration of a fuel cell includes estimating an initial amount of gas included at an anode side of a fuel cell, calculating a crossed over amount of gas between the anode side and a cathode side of the fuel cell and an amount of gas purged from the anode side to the outside from time when an initial amount of gas is predicted to a present time, and estimating a current hydrogen concentration at the anode side based on the predicted initial amount of gas, the calculated amount of crossed over gas, and the amount of purged gas.
