摘要 |
[Object] To increase contact conductivity with carbon and durability of a titanium or titanium alloy material for a fuel cell separator so as to increase the lifetime of a fuel cell. [Solution] Provided is a titanium or titanium alloy material for a fuel cell separator having a surface shape in which a plurality of projections are distributed, and a titanium oxide film on a surface of the projections. Fine projections are assumed to increase the contact conductivity remarkably. The present invention has high usability in the cell manufacturing industry. |
