Abstract
A metallic separator for a fuel cell including 2.2 to 6.0 parts by weight of tungsten based on 100 parts by weight of stainless steel containing molybdenum, and the weight ratio of molybdenum to tungsten (Mo/W) is 0.15 to 1.60. The separator for fuel cells has excellent anti-corrosive properties and contact resistance as low as that of a metal material, and thus, a fuel cell having high efficiency can be manufactured at a reasonable cost using the separator.
