Disclosed is a fuel cell system that stops producing electricity and exhausts residual electricity in an emergency situation. The fuel cell system includes a stack receiving a reactive gas including a hydrogen and/or an oxygen to produce the electricity, a pump supplying the reactive gas to the stack, a discharge circuit including a resistor that discharges a residual power in the stack and a first relay that electrically connects or disconnects the resistor to or from the stack, a generator connected to a rotational shaft of the pump to convert a driving energy of the rotational shaft of the pump to an electric energy, and a first controller controlling the first relay. The first controller receives the electric energy from the generator and controls the first relay to electrically connect the stack and the resistor such that the residual electricity in the stack is exhausted in the emergency situation.
