Abstract
Disclosed is a fuel cell stack comprising a fuel cell unit and separators which are stacked with each other. The separator is provided with a cooling medium supply port corresponding to a central portion of an electrode power-generating section and a cooling medium discharge port corresponding to an outer circumferential portion of the electrode power-generating section. The cooling medium supply port communicates with the cooling medium discharge port via a cooling medium flow passage having a spiral configuration. Accordingly, the entire fuel cell unit can be uniformly cooled, and the power-generating function can be effectively improved.
