Abstract
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.
