摘要： A fuel cell unit in which a hydrogen-side (anode) electrode and an air-side (cathode) electrode are disposed in facing relation to each other with an electrolyte membrane interposed therebetween, and wherein a separator is provided for supporting said fuel cell structure interposed therebetween. The separator has, independently disposed therein, a first cooling passage through which a first cooling medium, generally composed of water, is introduced for cooling the hydrogen-side electrode, and a second cooling passage through which a second cooling medium having a melting point below that of water is introduced for cooling the air-side electrode. Accordingly, a melting operation for the first cooling medium can be easily and swiftly carried out, while the fuel cell unit itself remains simple in structure.

摘要： 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.
摘要翻译：一种与燃料电池一起使用的气体加湿装置，其中透水膜设置有形成在透水膜的一侧上的燃料气体通道和含氧气体通道，并且其另一侧形成有加湿水通道。独立于水通道提供中等供应通道，用于供应熔点低于水的介质。因此，可以容易且快速地进行用于熔化加湿器内部的水的熔化操作，同时该装置的结构简单。

摘要： An apparatus for supplying a fuel gas comprises a reformer for steam reforming of methanol supplied from a methanol tank, and a methanol-removing means for removing unreacted methanol contained in the fuel gas delivered from the reformer. The fuel gas, from which the unreacted methanol is effectively removed, can be supplied to a fuel cell assembly. Accordingly, no unreacted methanol remains in the fuel gas to be supplied to an anode of the fuel cell. Thus the power generation performance can be effectively maintained.
