Provided are a low-price fuel cell separator with high corrosion resistance and a method for manufacturing the separator. The present disclosure relates to a fuel cell separator including a metal substrate and a titanium layer containing titanium formed on the metal substrate, and a method for manufacturing the separator. A ratio of a (100) plane to a sum of values obtained by dividing peak intensities of the (100) plane, a (002) plane, and a (101) plane derived from titanium in an X-ray diffraction analysis of a separator surface by respective relative intensities is a constant value or more.

Separator and method for manufacturing separator

A stainless steel substrate used for a fuel cell separator that is excellent in corrosion resistance is disclosed. The embodiments relate to a stainless steel substrate used for a fuel cell separator, comprising substantially no Nb, and comprising Ti.

Stainless steel substrate, fuel cell separator, and fuel cell

The present disclosure provides a stainless steel substrate used for a fuel cell separator that comprises Nb and is excellent in corrosion resistance. The embodiments relate to a stainless steel substrate used for a fuel cell separator, comprising Nb in a solid solution state, and comprising substantially no precipitate of a Nb-containing intermetallic compound.
