Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel cell stack configured by a plurality of cells that are stacked in a stacking direction, each cell including a power generating body and a pair of separators, wherein: 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, which is opposite to the first surface in the stacking direction, 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, and 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 in the stacking direction via the titanium nitride layer on the second surface. 2. The fuel cell stack according to claim 1 , wherein a thickness of the titanium nitride layer is from 10 to 200. 3. The fuel cell stack according to claim 2 , wherein a thickness of the carbon layer is about the same as the thickness of the titanium nitride layer.
