Abstract:
A fuel cell system comprising:a cooling line for cooling a fuel cell with a cooling fluid circulating between a fuel cell and a heat exchanger; a first water permeable membrane type humidifying apparatus for humidifying an oxidant gas supplied to a cathode inlet by exchanging moisture with a moisture rich cathode off-gas discharged from a cathode outlet of the fuel cell; a second water permeable membrane type humidifying apparatus for humidifying a fuel gas supplied to an anode inlet by exchanging moisture with a moisture rich off-gas discharged from an outlet of an anode or a cathode of the fuel cell; and a heating device for heating said oxidant and fuel gases with the cooling fluid in said cooling line, which absorbs heat from said fuel cell and flows into the heat exchanger.
