Problems solved by technology

[0006] On the other hand, since coolant channels are formed depending on hydrogen channels (anode channels) and air channels (cathode channels), conventional stamped and formed metal separators have difficulty in uniformly supplying cooling water to the reaction surface due to design limitations. question on
In particular, when cooling water is unevenly supplied onto the reaction surface, there is a problem that the temperature control of the reaction surface becomes uneven and the performance and durability of the fuel cell deteriorate

Abstract

The present invention relates to a separating plate and a fuel cell stack including same. According to an embodiment of the present invention, a separating plate is provided defining a coolant passagecapable of uniform coolant supply and heat recovery across all areas of a reaction region, the separating plate can easily regulate the temperature of a reaction surface, and a reduction in performance and durability due to thermal load can be prevented.

Description

technical field [0001] The present invention relates to a separator and a fuel cell stack including the separator. [0002] This application claims the benefit of priority based on Korean Patent Application No. 10-2015-0073872 filed on May 27, 2015, the disclosure of which is incorporated herein by reference in its entirety. Background technique [0003] Generally, a fuel cell system may include a fuel cell stack, a fuel supply portion that supplies fuel containing hydrogen to the fuel cell stack, and an air supply portion that supplies an oxidant containing oxygen necessary for electrochemical reactions of the fuel cell stack. The fuel cell system having the above-described structure generates electric power through an electrochemical reaction between fuel and air, and discharges heat and water as a by-product of the reaction. [0004] A fuel cell stack is formed by continuously disposing separators, wherein the separators may be respectively disposed on both sides of a me...
