Abstract
Official abstract text for this publication.
A separator for a fuel cell having a flow channel including a transverse channel and a longitudinal channel formed therein, the transverse channel having a pair of opposed side walls, and a first pattern and a second pattern alternately spaced and arranged in the transverse channel is provided. Each of the first pattern and the second pattern is a column-shaped three-dimensional structure having a polygonal transverse section. The first pattern and the second pattern are arranged in the transverse channel so as to have a shape of the transverse sections being rotated 180° relative to each other. First spacing distances from each of the first pattern and the second pattern to a first side wall of the pair of opposed side walls of the transverse channel are different.
First claim
Opening claim text (preview).
The invention claimed is: 1. A separator for a fuel cell comprising: a flow channel including a transverse channel and a longitudinal channel formed therein, the transverse channel having a pair of opposed side walls; and a first pattern and a second pattern alternately spaced and arranged in a single row in the transverse channel between the pair of opposed side walls, wherein the pair of opposed side walls of the transverse channel are parallel, wherein each of the first pattern and the second pattern is a column-shaped three-dimensional structure having a polygonal transverse section, wherein the polygonal transverse section has at least one internal angle that is greater or less than 90°, wherein the first pattern and the second pattern are arranged in the transverse channel so as to have a shape of the transverse sections being rotated 180° relative to each other, wherein first spacing distances from each of the first pattern and the second pattern to a first side wall of the pair of opposed side walls of the transverse channel are different, wherein second spacing distances from each of the first pattern and the second pattern to a second side wall of the pair of opposed side walls of the transverse channel are different, wherein the first spacing distances and the second spacing distances of the first pattern are different from each other, wherein the first spacing distances and the second spacing distances of the second pattern are different from each other, and wherein the polygonal transverse section is a trapezoid. 2. The separator for a fuel cell of claim 1 , wherein the flow channel is one or more types selected from among a serpentine-type, an interdigitated-type and a parallel-type. 3. A fuel cell comprising the separator for a fuel cell of claim 1 .
