Abstract
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.
