Abstract
An apparatus and method for controlling a purge valve of a fuel cell vehicle are provided to reduce a consumption amount of hydrogen and improve fuel efficiency. In particular, whether oxygen concentration in a channel of an anode of a fuel cell stack exceeds a reference value is estimated while restarting the vehicle after the vehicle is parked. Then, an open time of a purge valve is adjusted based on a parking time of a vehicle when the hydrogen concentration is greater than the reference value.
