Abstract
Disclosed herein is an air shut-off valve for a fuel cell system that can completely close an air passage (11) communicating with a cathode of a fuel cell stack, even though a butterfly-type valve is employed, upon the halt of operation of the fuel cell system, thereby greatly improving the durability of the fuel cell stack.
