FUEL CELL STACK

摘要

This fuel cell stack (100) comprises a plurality of cells (10) stacked in a stacking direction. Each cell (10) comprises a power generation element (1) and a pair of separators (2) that are respectively arranged on both surfaces of the power generation element (1) in the stacking direction. Each separator (2) has a first surface (2a) and a second surface (2b). A titanium nitride layer (3) is formed on the first surface (2a), and a conductive carbon layer (4) is formed on the titanium nitride layer (3). A titanium nitride layer (3) is formed on the second surface (2b). Each separator (2) is in contact with the power generation element (1), with the titanium nitride layer (3) and the carbon layer (4) on the first surface (2a) being interposed therebetween, while being in contact with one separator (2) of another adjacent cell (10), with the titanium nitride layer (3) on the second surface (2b) being interposed therebetween.
