Abstract
A hydrogen supply control method of a fuel cell system is provided. The method includes measuring the pressure of a front line of a supply line having relatively low humidity and the pressure of a front end of an ejector, without a pressure sensor of an anode. The amount of supplied hydrogen is then adjusted using the measured pressure and the pressure of the anode is estimated more accurately.
