摘要： A metallic bipolar plate for a fuel cell, in which a carbon coating layer containing fluorine is formed on the surface of a stainless steel base material, thus having excellent electrical conductivity and corrosion resistance and further excellent water draining performance and heat radiating performance. In the metallic bipolar plate for a fuel cell of the present invention, the internal residual stress in the surface coating layer is significantly reduced due to the addition of fluorine, and thereby it is possible to improve the adhesive strength between the stainless steel and the surface coating layer.
