Abstract: An apparatus and method for reducing an exhaust hydrogen concentration in a fuel cell system includes a first air cut-off valve (ACV) blocking ambient air supplied to a cathode, a second ACV blocking exhaust hydrogen discharged from the cathode, and an air suction valve (ASV) operating in a first mode connecting the cathode and an intake port of an air compressor and in a second mode blocking connection between the cathode and the intake port of the air compressor. The apparatus also includes a controller for operating the ASV in the first mode to store air of the cathode while the first ACV is opened and the second ACV is closed when hydrogen is supplied to an anode, and for operating the ASV in the second mode to discharge ambient air through an exhaust line while the first ACV is opened and the second ACV is opened when ambient air is supplied to the cathode.
