Abstract
A method of controlling hydrogen concentration of a fuel cell includes calculating hydrogen or nitrogen concentration of gas stored in a fuel tank; estimating hydrogen or nitrogen concentration at an anode of the fuel cell based on the calculated hydrogen or nitrogen concentration of the gas; and controlling a hydrogen supply unit based on the estimated hydrogen or nitrogen concentration at the anode such that the hydrogen or nitrogen concentration at the anode follows desired hydrogen concentration or desired nitrogen concentration.
