摘要：
The present invention provides a novel integrated valve system for a fuel cell stack, in which an air shut-off valve for preventing the inflow of air when a fuel cell shuts down and a dry gas purge valve for improving cold startability are coaxially coupled to each other so that the air shut-off valve and the dry gas purge valve simultaneously open or close.
