Abstract
A system for estimating a concentration of hydrogen in a fuel cell is provided. The system includes a hydrogen supply line supplying the hydrogen to the fuel cell and a time measurement sensor measuring a time duration from a point in time when an operation of the fuel cell ends to a point in time when the fuel cell restarts. A controller estimates an amount of air introduced into the fuel cell during the time duration using the measured time duration and estimates a concentration of hydrogen in the hydrogen supply line at the time of restarting the fuel cell based on the measured time duration and the estimated amount of introduced air.
