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.

Claim (Index 19):
The system of  claim 18 , wherein the hydrogen concentration estimator determines the air processing system to be an open model when the measured flow rate of the air exceeds the predetermined flow rate, and determines the air processing system to be a closed model when the measured flow rate of the air is equal to or less than the predetermined flow rate.
