1. A fuel cell system that generates electric power by supplying anode gas and cathode gas to a fuel cell, comprising:
a control valve adapted to control a pressure of the anode gas to be supplied to the fuel cell;
a buffer unit adapted to store an anode-off gas to be discharged from the fuel cell; and
a controller programmed to:
control the control valve in order to periodically increase and decrease the pressure of the anode gas at a specific width of a pulsation,
correct the width of the pulsation based on a temperature of the buffer unit, and
decrease the width of the pulsation when the temperature of the buffer unit is lower than a steady temperature of the fuel cell.
