<P>PROBLEM TO BE SOLVED: To provide a conductive resin coated body of a separator for a fuel cell having excellent wear resistance and long-term durability, miniaturizing a fuel cell body and reducing the contact resistance value of a metallic separator and a gas diffusion electrode while exhibiting sufficient corrosion resistance without using noble metal. <P>SOLUTION: The separator for the fuel cell is formed by coating at least one side of a metal substrate with at least one conductive resin layer. The mass ratio of conductive ceramics to binder resin in the conductive resin layer is set to 30/70 to 70/30, the thickness of the conductive resin layer is in a range of 0.5-10 μm, and pencil hardness of the conductive resin layer measured according to JIS K5400 is 5B or more. <P>COPYRIGHT: (C)2008,JPO&INPIT |
