Claim Text:
1. A closed loop type fuel cell system with unreacted material removing function, comprising: a main fuel cell reacting an oxidant and a reductant to generate electricity; a supply member configured to supply material containing the oxidant and the reductant for the main fuel cell; a recirculating member configured to recirculate unreacted material discharged from the main fuel cell back into the main fuel cell; a detecting member configured to detect voltages of a plurality of cells composing the main fuel cell; a regenerating member configured to selectively communicate to one side of the main fuel cell to remove moisture and impurities inside the main fuel cell; an exhausting member configured to circulate unreacted material remnant inside the regenerating member through the regenerating member to exhaust the unreacted material; and a control member configured to control actions of the supply member, the recirculating member, the detecting member, the regenerating member, and the exhausting member; wherein the exhausting member includes a collecting pipe and one side of the collecting pipe has a collecting pump forcing the unreacted material to flow into a sacrificial fuel cell; and wherein the exhausting member includes an exhauster configured to store or extinguish electricity generated in the sacrificial fuel cell to exhaust the oxidant and the reductant inside the sacrificial fuel cell.
