SEPARATOR FOR FUEL CELL

A separator for fuel cells includes a number of lands arranged in columns and configured to contact and support a membrane electrode assembly and a number of channels configured to form a movement path of a reaction gas. Each channel is located between two adjacent lands. Branch parts of the lands are arranged in a first column and in an adjacent second column in a moving direction of the reaction gas. The branch parts of the lands in the first column and in the second column are arranged in a discontinuous form. Width-directional or height-directional lengths of the lands are selectively changed so that a flow rate deviation of the moving reaction gas occurs.
