ANTI-CORROSION CONDUCTIVE MATERIAL, SOLID POLYMER TYPE FUEL CELL AND SEPARATOR THEREOF, AND METHOD OF MANUFACTURING ANTI-CORROSION CONDUCTIVE MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an anti-corrosion conductive material excellent in corrosion resistance and conductivity.

SOLUTION: This anti-corrosion conductive material includes a Ti base material comprising pure titanium (Ti) or a Ti alloy, and anti-corrosion conductive coating film formed on a surface of at least one part of the base material and excellent in at least one of the corrosion resistance and the conductivity, and the anti-corrosion conductive coating film is a titanium phosphide coating film. The titanium phosphide coating film is inexpensive compared with a conventional coating film using noble metal, and exhibits very excellent corrosion resistance or conductivity.
