Abstract
A fuel cell stack includes a plurality of cells that are stacked in a stacking direction. Each cell includes a power generating body and a pair of separators. The separators respectively are arranged on opposite surfaces of the power generating body in the stacking direction. Each separator includes a first surface and a second surface. A titanium nitride layer is formed on the first surface, and a conductive carbon layer is formed on the titanium nitride layer. A titanium nitride layer is formed on the second surface. Each separator is in contact with the power generating body via the titanium nitride layer and the carbon layer on the first surface and is in contact with one of the separators of an adjacent cell via the titanium nitride layer on the second surface.
