ABSTRACT:
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.
