Abstract
A fuel cell system comprises: a fuel cell stack () where an anode () and a cathode () are arranged under a state that an electrolyte membrane is positioned therebetween; a fuel tank () for storing a fuel; a fuel circulation supply means () for circulation-supplying a fuel stored in the fuel tank () to the anode of the fuel cell stack; an air supply unit () connected to the cathode of the fuel cell stack () by an air supply line, for supplying oxygen, etc. to the cathode (); a sensing unit () for measuring a concentration of at least one of fuels supplied to the anode () and a control unit for receiving a signal of the sensing unit () and informing replacement time of a fuel. According to this, a fuel usage is maximized by informing replacement time of a used fuel and a filter () for filtering impurity by detecting a fuel consumption degree and an impurity generation amount.
