Zusammenfassung:The present invention provides an apparatus and a method for controlling hydrogen purging. The apparatus includes a purging valve that is provided for an outlet disposed adjacent to an anode of a fuel cell stack and is configured to adjust an outflow of water from the fuel cell stack. In addition, a controller is configured to adjust an opening of the purging valve according to a charge capacity obtained by integrating a current capacity of the fuel cell stack. The controller is configured to calculate the charge capacity by multiplying the current capacity of the fuel cell stack by a scale factor when a load for an output current of the fuel cell stack is less than a first reference load which is preset.
