Abstract: A fuel cell system is disclosed. The fuel cell system includes a stack unit including a fuel electrode and an air electrode and generating electricity by an electrochemical reaction between hydrogen and oxygen; a fuel supply unit supplying hydrogen to the fuel electrode of the stack unit; an air supply unit supplying the air to the air electrode of the stack unit; and a residual gas storage unit storing residual hydrogen exhausted from the stack unit or the fuel supply unit and then supplying the residual hydrogen to the stack unit again or to another system requiring hydrogen. The residual gas storage unit of the fuel cell system allows residual hydrogen to re-supplied to the stack unit if necessary, so that a waste of raw materials for generating hydrogen can be reduced and thus a cost can be reduced.
