Abstract
In a fuel cell system and a method of controlling the same, a fuel cell stack is connected at its downstream side with a hydrogen control valve and a hydrogen draw pump . A control unit controls the hydrogen draw pump such that hydrogen drawing power is increased to a level larger than that required for normal operation and controls the hydrogen control valve such that opening degree is decreased. After that, the control unit controls the hydrogen control valve such that the opening degree is increased to purge moisture in the fuel cell stack.
