A gas humidifying device (10) for use with a fuel cell (12) in which water permeable membranes (22a-22f) are provided with fuel gas passages (34a-34c) and oxygen-containing gas passages (48a-48c) formed on one side of the water permeable membranes, and wherein humidifying water passages (40a-40f, 144) are formed on the other side thereof. Medium supply passages (44, 150) 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 (14) can be easily and swiftly carried out, while the device remains simple in structure. <IMAGE> |
