Abstract
A closed loop type fuel cell system is provided including a recirculating unit that recirculates hydrogen and oxygen discharged from a main fuel cell into the main fuel cell and a reproducing unit that removes water produced in operation of the main fuel cell and impurities contained in the circulated hydrogen and oxygen. Further, a closed loop type fuel cell is provided that makes it possible to generate electricity by using a main fuel cell and purify water and impurities by allowing a side of a recirculating unit to selectively communicate with a side of a reproducing unit. Further, a closed loop type fuel cell is provided that is precluded by being damaged by precluding reduction of efficiency of electric generation of a main fuel cell by selectively replacing a sacrifice fuel cell in a reproducing unit.
