TITANIUM PRODUCT, SEPARATOR AND FUEL ELEMENT WITH PROTON-EXCHANGE MEMBRANE AND METHOD FOR MANUFACTURING OF TITANIUM PRODUCT Russian patent published in 2018 - IPC H01M8/202 H01M8/10 C23C8/12

Abstract RU 2660484 C1

FIELD: technological processes.

SUBSTANCE: invention relates to a titanium product for a separator of a fuel element with a proton-exchange membrane, a separator comprising this titanium product, and a fuel element with a proton-exchange membrane. Titanium product includes a base material that consists of pure titanium. First oxide layer that is formed in the surface layer of the titanium product consists of TiO₂ with the crystal structure of rutile and has a thickness of 0.1–1.5 nm. Second oxide layer that is formed between the base material and the first oxide layer consists of TiO_x (1<x<2) and has a thickness of 3–20 nm. This titanium product is suitable for use as a separator of a fuel element with a proton-exchange membrane.

EFFECT: invention makes it possible to maintain a low contact resistance with an electrode composed of a carbon fiber, et cetera, and is also inexpensive.
