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 5):
The method of  claim 3 , wherein when the air processing system is determined to be the open model, when estimating the hydrogen concentration of the fuel processing system, nitrogen partial pressure or oxygen partial pressure of the air processing system is based on gas pressure and water vapor partial pressure of the air processing system.
