Protective-layer-coated-interconnector, cell stack including this protective-layer-coated-interconnector, and fuel cell including the same
Provided is a protective-layer-coated-interconnector, a cell stack, and a fuel cell. A component (particularly Cr) of the 5 interconnector is prevented from diffusing even if the interconnector is exposed to high temperature for a long time. The interconnector has sufficient diffusion barrier-performance and protective performance even with a protective layer thinner than conventionally, is inhibited from being degraded through 10 use, and has excellent electrical conductivity, adhesion, heat cycle resistance, and the like. [Solution] A protective-layer-coated-interconnector, a cell stack including the interconnector, and a fuel cell including the interconnector, wherein the interconnector includes an 15 interconnector material and a protective layer on the surface of the interconnector material, wherein the interconnector material is composed of a Fe-Cr alloy containing a rare earth element or a Zr element in a total amount of 1.0 weight% or less, and wherein the protective layer is composed of a Co oxide or an 20 oxide containing: at least one element selected from the group consisting of Al, Ti, Cr, Fe, Ni, Cu, and Zn; and a Co element.
