Fuel cell separator and process for its production |
摘要 |
The present invention provides a fuel cell separator comprising a metallic substrate and an amorphous carbon film covering at least a surface of the substrate facing an electrode, the amorphous carbon film comprising carbon and hydrogen and being characterized in that it contains not more than 30 atomic % (excluding 0 atomic %) of hydrogen and, when the entire amount of the carbon is taken as 100 atomic %, carbon having an sp2 hybrid orbital is present in an amount of not less than 70 atomic % and less than 100 atomic %, wherein the amount of carbon having an sp2 hybrid orbital is determined by 13 C nuclear magnetic resonance using high-power decoupling with magic angle spinning, as well as a process for forming the same. |
