Abstract
A system for estimating purge of a fuel cell includes the fuel cell for generating power by receiving hydrogen at an anode side, and receiving oxygen at a cathode side, a recirculation line connected with the anode side of the fuel cell, and in which gas containing hydrogen therein is circulated, a purge valve positioned in the recirculation line, and for discharging the gas in the recirculation line to outside as the purge valve is opened, a differential pressure calculator for calculating a differential pressure between a front end and a rear end of the purge valve, a speed estimator for estimating a current gas diffusion speed in the recirculation line, and a purge amount estimator for estimating the amount of purge through the purge valve by using the differential pressure calculated by the differential pressure calculator and the gas diffusion speed estimated by the speed estimator.
