SEALED FUEL CELL SYSTEM

摘要

The present invention relates to a sealed fuel cell system. According to an embodiment of the present invention, the sealed fuel cell system comprises: a main fuel cell which produces electricity by reacting fuel with oxygen; a supply means which supplies a gas including the fuel and the oxygen to the main fuel cell; a recirculation means which recirculates the gas, which includes the oxygen and hydrogen that are discharged from the main fuel cell, to the main fuel cell; a sensing means which senses a plurality of cell voltages that constitute the main fuel cell; a reproduction means which is selectively communicated with one side of the main fuel cell and eliminates moisture and impurities from the inside of the main fuel cell; and a controlling means which controls the operation of the supply means, the recirculation means, the sensing means, and the reproduction means. The reproduction means comprises: a reproduction pipe which guides the flowing direction of the gas that includes the hydrogen and the oxygen passing through the recirculation means; a reproduction valve which selectively shields the reproduction pipe; a regenerative fuel cell which generates water by reacting the gas including the hydrogen and the oxygen provided from the reproduction pipe inside the regenerative fuel cell; and a water gathering unit which gathers water generated from the regenerative fuel cell. According to the present invention, the risk of explosion caused by the discharge of hydrogen is resolved, and the generation efficiency and durability of the main fuel cell can be improved because moisture and impurities are eliminated.
