| titleOfInvention | Stainless steel for polymer fuel cell separator and manufacturing method |
| abstract | The present invention relates to a method for manufacturing stainless steel for polymer fuel cell separators having low interfacial contact resistance through surface modification. Stainless steel according to the present invention for achieving the above object, in weight percent, C: greater than 0 0.02 or less, N: greater than 0 0.02 or less, Si: greater than 0 0.4 or less, Mn: greater than 0 0.2 or less, P: greater than 0 0.04 or less, S: more than 0 and 0.02 or less, Cr: 25 to 34, Mo: less than 0 to 2.5, Cu: 0 to 1, Ni: less than 0 to 0.2, Ti: more than 0 and less than 0.5, Nb: more than 0 and less than 0.5 The ferritic stainless steel containing at least one of V: more than 0.2 and 1 or less, and W: more than 0 and 4 or less, wherein the stainless steel surface passivation coating is formed by adjusting the composition, temperature, and immersion time of the sodium hydroxide solution. It has a hydroxide / oxide ratio, in particular at least two Cr hydroxide / Cr oxide ratios. By such a configuration, it has a low interfacial contact resistance and can produce stainless steel suitable for a polymer fuel cell. |
