Abstract:
A hydrogen concentration estimating method for a fuel cell includes: measuring a flow rate of air supplied to a fuel cell stack, and comparing the measured flow rate of the air with a predetermined flow rate; determining a model of an air processing system according to a comparison result; and estimating hydrogen concentration of a fuel processing system based on the determined model of the air processing system.
