Abstract:
A fuel cell stack includes cell units and separators that are alternately stacked, in which each of the cell units includes a single cell. Each of the separators includes: at least one first ridge that is disposed on a first main surface of each of the separators at a predetermined interval to form at least one first gas channel; and at least one second ridge that is disposed on a second main surface of each of the separators at a predetermined interval to form at least one second gas channel. The at least one first ridge and the at least one second ridge are disposed at a regular interval around a center of each of the separators in a cross section perpendicular to the first or second gas channel. The at least one first ridge and the at least one second ridge of the separators are arranged such that a first ridge and a second ridge of a first separator of two of the separators holding each cell unit at least partly overlap respectively with a second ridge and a first ridge of a second separator of the two of the separators in a stacking direction of the separators across a single cell intervened between the two of the separators.

Claim (Index 22):
The fuel cell stack according to  claim 17 ,\n wherein at least one first protrusion is disposed at a predetermined interval to form the at least one first gas channel, at least one second protrusion is disposed at a predetermined interval to form the at least one second gas channel, the at least one first protrusion is disposed point symmetrical to the at least one second protrusion with respect to the center of each of the separators in in-plane rotation and protrudes in a direction opposite to a direction of protruding the second protrusion, and the at least one first protrusion and the at least one second protrusion of the separator are arranged such that the at least one first protrusions and the at least one second protrusions of the two of the separators that hold each of the cell units overlap with each other in the stacking direction of the separators.
