Transition metal nitride, fuel cell separator, method for producing transition metal nitride, method for producing fuel cell separator, fuel cell stack, and fuel cell vehicle |
摘要 |
A transition metal nitride comprises a first layer formed of a nitride of a steel containing at least Fe ad Cr and second layer formed on a first layer and having an exposed surface. The transition metal nitride has a composition distribution in which Cr concentration is continuously changed from the first layer to the second layer in a thickness direction of these layers. A fuel separator comprises a base layer formed of a stainless steel containing at least Fe and Cr and a nitride layer formed of a transition metal nitride as described. Methods of forming transition metal nitrides and fuel cell separators are also included, as is a fuel cell vehicle including a fuel cell stack. |
