Abstract
A humidification device for a fuel battery system, which rapidly exchanges dry air with humid air over a wide area, thus increasing humidification efficiency, and which appropriately heats dry air and humid air during cold weather, thus preventing the moisture of humid air from freezing, therefore being effectively used in cold regions. The humidification device includes a hollow fiber membrane to pass dry air and humid air so that moisture exchange is conducted between the dry air and the humid air, and a dry air guide pipe to supply new dry air into the hollow fiber membrane.
