Abstract
Official abstract text for this publication.
An object is to equalize the level of cooling along a top-bottom direction of a fuel cell stack. A fuel cell stack has an anode-side separator placed between a plurality of membrane electrode assemblies. The anode-side separator comprises a separator center area that is arranged to face a power generation area of the membrane electrode assembly; an outer peripheral portion that is extended from the separator center area to outer periphery and has a plurality of openings for cooling medium supply manifolds; and a rib that is firmed from a beam portion provided to separate the adjacent openings for cooling medium supply manifolds from each other, over an area between the openings for cooling medium supply manifolds and the separator center area.
First claim
Opening claim text (preview).
What is claimed is: 1 . A separator for fuel cell that is used in a fuel cell stack, the separator for fuel cell comprising: a center area; an outer peripheral portion that is an area outside of the center area and has a plurality of openings for manifolds formed therein; and a rib that is formed from a beam portion provided to separate the openings for manifolds from each other, over an area between the openings for manifolds and the center area. 2 . The separator for fuel cell according to claim 1 , wherein the rib is inclined in the area between the openings for manifolds and the center area. 3 . The separator for fuel cell according to either claim 1 or claim 2 , wherein the opening for manifold is an opening provided to form a cooling medium supply manifold that is configured to supply a cooling medium to the center area. 4 . A fuel cell stack in which a plurality of membrane electrode assemblies are stacked with a separator for fuel cell placed therebetween, wherein the separator for fuel cell comprises: a center area that is arranged to face a power generation area of the membrane electrode assembly; an outer peripheral portion that is an area outside of the center area and has a plurality of openings for manifolds for a cooling medium formed therein; and a rib that is formed from a beam portion provided to separate the openings for manifolds from each other, over an area between the openings for manifolds and the center area. 5 . The fuel cell stack according to claim 4 , wherein the separator for fuel cell is provided on an anode side of the membrane electrode assembly.
