Document Type and Number:
WIPO Patent Application WO/2023/095648
Kind Code:
A1
Abstract:
The present invention provides a titanium material for fuel cell separators, the titanium material being used for a fuel cell separator and being capable of decreasing the contact resistance between separators, while being also capable of suppressing an increase of the contact resistance in a cooling water environment. A titanium material (1) for fuel cell separators according to the present invention is provided with: a titanium foil base material (2) that has a first surface (one surface (2a)) and a second surface (the other surface (2b)), which are perpendicular to the thickness direction; and a conductivity holding film (5) that is formed at least on the first surface (2a) of the titanium foil base material (2). The conductivity holding film (5) comprises a TiC layer (3); the TiC layer (3) is in direct contact with the titanium foil base material (2); and at least a part of the TiC layer (3) is exposed in the surface of the conductivity holding film (5).
