Abstract
Provided is a high-temperature fuel cell separator. The fuel cell separator includes a fuel gas flow path containing hydrogen, an oxidant gas flow path containing mainly an oxygen component being supplied from an oxygen/nitrogen separator of a system and participating in electrochemical reactions, and a cooling gas flow path containing a nitrogen component to remove heat produced upon power generation of a fuel cell. Such a configuration provides a high-temperature fuel cell separator which is capable of improving efficiency of an overall fuel cell system through improved performance of a fuel cell stack due to increased oxygen partial pressure and which is also capable of improving reliability of the fuel cell stack through inhibition of the occurrence of a high-temperature region resulting from heat produced upon power generation of a fuel cell, by means of a flow of cooling gas containing a nitrogen component.
