SEPARATION PLATE OF FUEL CELL FOR HIGH-TEMPERATURE SERVICE APPLICATION

摘要

PROBLEM TO BE SOLVED: To provide a separation plate of a fuel cell for high-temperature application capable of improving performance rather than a conventional fuel cell by raising partial pressure of oxygen in a passage of an air electrode where an electrochemical reaction is occurred so that the passages for oxygen and nitrogen are separated inside the separation plate of a fuel cell and effectively removing heat generated at the time of development through a passage of a nitrogen gas or the like.

SOLUTION: The separation plate of a fuel cell for high-temperature application comprises a fuel gas passage including hydrogen, an oxidizer gas passage mainly including an oxygen component which joins to an electrochemical reaction by being supplied from an oxygen/nitrogen separator of a system, and a cooling gas passage including a nitrogen component in order to remove heat generated at the time of development of the fuel cell. Thus, efficiency of the whole fuel cell system on the basis of improved performance of a fuel cell stack can be improved with increase of partial pressure of the oxygen, and reliability of the fuel cell stack can be improved by restraining generation of a high-temperature section caused by heat generated at the time of development of the fuel cell on the basis of a flow of the cooling gas including the nitrogen component.
