    Abstract: A transition metal nitride comprises a first layer formed of a nitride of a stainless steel containing at least Fe and Cr and a second layer formed on the first layer and having an exposed surface. The second layer is formed of another nitride having contents of components that differ from those in the first layer. The first and second layers have a composition distribution in which a Cr concentration is continuously changed from the first layer to the second layer in a thickness direction of these layers, and the second layer has a nitride deposition protruding from a base portion of an exposed surface. A fuel cell 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.

    Abstract: An air cell includes a positive electrode layer, an electrolyte layer stacked on the positive electrode layer, a negative electrode layer stacked on the electrolyte layer and an electroconductive liquid-tight ventilation layer stacked on the positive electrode layer, the electroconductive liquid-tight ventilation layer being positioned on the opposite side of the positive electrode from the electrolyte layer. The assembled battery is provided with a plurality of the air cells described above. The assembled battery is provided with a flow path through which oxygen-containing gas flows interposed between the electrically-conductive liquid-tight ventilation layer of a first air cell and the negative electrode layer of a second air cell adjacent to the first air cell. The first air cell is electrically connected to the negative electrode layer of the second air cell via the electrically-conductive liquid-tight ventilation layer.
