Abstract
An open type fuel cell system is provided including a recirculating unit that recirculates hydrogen discharged from a main fuel cell into the main fuel cell and a reproducing unit that removes water and impurities produced in operation of the main fuel cell. The open type fuel cell system is adapted so that it does not discharge hydrogen supplied to a main fuel cell into the atmosphere.
