Embodiment Construction
[0070] As described herein, the present invention includes a separator for a fuel cell stack comprising: a channel portion including a plurality of cooling water flow channels formed therethrough; a hydrogen flow channel and a plurality of air flow channels formed on the other outer surface thereof; a guide part integrally formed on one end thereof with both ends of the channel part, respectively; and a manifold part integral with the other end of the guide part formed and have cooling water inlet and outlet manifolds, wherein a partition plate is arranged between the manifold portion and the guide portion, and the partition plate is formed penetratingly therein with the cooling water inlet and the cooling water outlet.
[0071] In one embodiment, in the channel portion, the hydrogen flow channels and the air flow channels and the cooling water flow channels are alternately arranged to face each other.
[0072] In another embodiment, the guide portion has an inner space formed...

Abstract
The present invention provides a separating plate for a fuel cell stack and method of manufacturing the same, and more particularly, to a separating plate for a fuel cell stack and method of manufacturing the same, in which the separating plate constituting the fuel cell stack is formed in such a fashion as to interpose an array of metal pipes between two sheets of composite material, and a gasket abutting against the separating plate is formed in such a fashion as to define hydrogen and air flow channels, thereby removing a contact resistance between two adjoining separating plates constituting unit cells to improve the efficiency of the fuel cell.
Description
[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119(a) to Korean Patent Application No. 10-2008-055008 filed June 12, 2008, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a separator for a fuel cell stack and a manufacturing method thereof, and more particularly, to a separator for a fuel cell stack and a manufacturing method thereof, wherein the separator of the fuel cell stack is constituted to be in two It is formed by inserting a row of metal tubes between sheet composite materials, and the gaskets close to the separator are formed in such a way as to form hydrogen flow channels and air flow channels, thereby eliminating the gap between two adjacent separators that constitute unit cells. contact resistance to properly improve the efficiency of the fuel cell. Background technique [0004] Fuel cells are zero-emission power generating devices th...
