ABSTRACT:
A gas humidifying device for use with a fuel cell in which water permeable membranes are provided with fuel gas passages and oxygen-containing gas passages formed on one side of the water permeable membranes, and wherein humidifying water passages are formed on the other side thereof. Medium supply passages are provided independently from, yet in proximity to the water passages, for supplying a medium having a melting point lower than that of water. Accordingly, a melting operation for melting the water in the interior of the humidifier can be easily and swiftly carried out, while the device remains simple in structure.
