Abstract
The present disclosure relates to an apparatus for controlling an operation of a fuel cell system and a method therefor. The present disclosure may include a voltage sensor that measures an output voltage of a fuel cell stack, an air compressor that supplies air to a cathode of the fuel cell stack, a valve driver that adjusts an opening degree of an Airflow Control Valve (ACV), and a controller that, in an idle stop state, drives the air compressor at a lowest level and controls the opening degree of the ACV such that the output voltage of the fuel cell stack maintains a reference range.
