Patent ID: 8460833

Claim:
An open type fuel cell system with an unreacted material removing function, comprising: a main fuel cell reacting an oxidant and a reductant to generate electricity; a means for supplying material including an oxidant and a reductant for the main fuel cell; a means for recirculating unreacted material discharged from the main fuel cell into the main fuel cell; a detector detecting voltages of a plurality of cells composing the main fuel cell; a means for regenerating selectively communicating to one side of the main fuel cell to remove moisture and impurities inside the main fuel cell; a means for humidification supplying moisture discharged from the main fuel cell, into the main fuel cell; a means for exhausting circulating and exhausting inside the regenerating means unreacted material remnant inside the regenerating means; and a controller controlling actions of the means for supplying, the means for recirculating, the detector, the means for regenerating, the means for humidification, and the means for exhausting, wherein the means for regenerating includes a sacrificial fuel cell reacting oxidant and reductant from unreacted material provided from the main fuel cell, for electricity generation, and wherein the means for exhausting includes: an exhauster storing or discharging electricity generated in the sacrificial fuel cell to exhaust fuel inside the sacrificial fuel cell; a collecting pipe guiding unreacted material and impurities coming from the sacrificial fuel cell into the sacrificial fuel cell; a purge pipe branching from the collecting pipe and selectively opening an inner part of the sacrificial fuel cell; a pressure gauge measuring pressure inside the sacrificial fuel cell; and an ampere meter measuring a current amount occurring from the sacrificial fuel cell at one side of the exhauster.
