Abstract
A separator for fuel cell includes a corrugated portion formed to have a corrugated cross section where a first groove that is concave to a first surface to form a flow path for a first fluid on the first surface and a second groove that is concave to a second surface opposite to the first surface to form a flow path for a second fluid on the second surface are arranged alternately and repeatedly. Each of the second grooves has at least one shallower groove section formed to have a less depth from the second surface than depth of a remaining groove section and provided to form a communication flow channel on the first surface side, which is arranged to communicate between two flow path spaces for the first fluid that are adjacent to each other across the shallower groove section.
