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 18):
A hydrogen concentration estimating system for a fuel cell, the system comprising:\n an air processing system supplying air to a fuel cell stack; a fuel processing system supplying hydrogen to the fuel cell stack; and a hydrogen concentration estimator measuring a flow rate of the air supplied to the fuel cell stack from the air processing system, comparing the measured flow rate of the air with a predetermined flow rate, determining a model of the air processing system, and estimating hydrogen concentration of the fuel processing system based on the determined model of the air processing system.
