TITANIUM-BASED MATERIAL OR A TITANIUM ALLOY-BASED MATERIAL WITH SURFACE ELECTRICAL CONDUCTIVITY, AND ITS METHODS OF MANUFACTURING, AND FUEL CELL SEPARATOR, FUEL CELL USING IT Russian patent published in 2017 - IPC H01M8/02 

FIELD: metallurgy.

SUBSTANCE: titanium-based material or a titanium alloy-based material, in which as part of an oxide film formed on the surface of titanium or titanium alloy, the composite ratio for TiO(I_TiO/(I_Ti+I_TiO))×100, determined from the peak intensities in the X-ray diffraction pattern for TiO (I_TiO) and the peak intensities in the X-ray diffraction pattern for metallic titanium (I_Ti) for X-ray diffraction, measured at a magnitude of the radiation incidence angle to the surface of 0.3°, is 0.5% or more. There is also a method for producing a titanium-based material, a fuel cell separator and a fuel cell based on a polymer electrolyte.

EFFECT: group of inventions allows the production of a titanium-based material or a titanium alloy-based material characterized by excellent electrical conductivity in contact with carbon and excellent durability.
