Nitrogen reprocessing fuel cell system

Abstract

According to one aspect of the present invention, a nitrogen reprocessing fuel cell system is provided, comprising: a fuel cell module; a hydrogen-nitrogen gas tank that stores hydrogen and nitrogen discharged from the fuel cell module and has nitrogen pre-filled at atmospheric pressure; an oxygen-nitrogen gas tank that stores oxygen and nitrogen discharged from the fuel cell module and has nitrogen pre-filled at atmospheric pressure; a nitrogen extractor connected to at least one of the hydrogen-nitrogen gas tank and the oxygen-nitrogen gas tank; a pressure switch that measures the pressure of nitrogen from the nitrogen extractor; a compressor that compresses the nitrogen from the nitrogen extractor in response to an operating instruction from the pressure switch; a nitrogen supply tank that receives and stores the compressed nitrogen from the compressor; and a nitrogen supply pipeline that transfers the nitrogen from the nitrogen supply tank to the fuel cell module.
