Abstract: A fuel cell is provided that includes a cell stack having a plurality of unit cells stacked in a first direction. An enclosure is disposed to surround the cell stack and includes an inlet that suctions external air and an outlet that discharges air that has been suctioned through the inlet and has circulated in the space between the cell stack and the enclosure. An insulating member is disposed to extend in the first direction in the space between an outer surface of the cell stack and an inner surface of the enclosure. The insulating member divides the space into a plurality of spaces and has an aperture formed therein to provide communication between the divided plurality of spaces, and an air intake member configured to suction air discharged from the outlet.

Abstract: An air processing system of a fuel cell vehicle mounted with an integrated valve includes: the integrated valve attached to an air inlet and an air outlet formed integrally with a fuel cell stack and adjusting amounts of air introduced into and discharged from the fuel cell stack. The integrated valve is positioned at the shortest distance from the fuel cell stack, such that an amount of remaining oxygen that is to be consumed at the time of stopping start of a fuel cell vehicle is minimized. Therefore, corrosion of cathode carbon is decreased as compared with the related art, such that durability of the fuel cell vehicle is improved.

Abstract: A fuel cell system includes a fuel cell stack including an air electrode and a fuel electrode, a stack housing having a hollow therein to accommodate the fuel cell stack in the hollow, an air compressor configured to pump air to supply the air to the air electrode, a ventilation pipe connecting an entrance of the air compressor and the hollow, and at least one vent hole provided on an outer wall of the stack housing such that the hollow and an outside of the stack housing communicate with each other. An interior of the stack housing is ventilated by lowering of a pressure at the entrance of the air compressor, which is generated as the air compressor is operated, while air outside the stack housing is suctioned into the entrance of the air compressor after passing through the vent hole, the hollow, and the ventilation pipe.
