FE-NI/CR-CNT METAL SEPARATOR FOR FUEL CELL AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: An iron-nickel/chrome-carbon nanotube metal separation plate is provided to have excellent intensity, hardness, durability, corrosion resistance and/or electric conductance. CONSTITUTION: An iron-nickel/chrome-carbon nanotube metal separation plate comprises an alloy of iron and nickel, and chrome and carbon nanotube-containing layers formed on both sides of an alloy thin-film of the iron and nickel. A flow path shape of the separation plate for a fuel cell is formed in the iron-nickel/chrome-carbon nanotube metal separation plate. The alloy thin-film of the iron and nickel has a thickness of 30-70 um and comprises 5-30 wt% of nickel and a remaining content of iron and other unavoidable impurities. The chrome and carbon nanotube-containing layer has a thickness of 0.1-20 um and comprises 10-50 wt% of carbon nanotubes and a remaining content of chrome and other unavoidable impurities.
