摘要： [Problem] Provided are a protective-layer-coated-interconnector, a cell stack, and a hydrogen energy system. A component (particularly Cr) of the 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 use, and has excellent electrical conductivity.
[Solution] A protective-layer-coated-interconnector including an interconnector material and a protective layer on the surface of the interconnector material, wherein the protective layer contains a metal layer constituted by a Group 11 element. A cell stack and a hydrogen energy system that each include this interconnector.-

摘要： A metal component for electrochemical stack in an embodiment includes: a metal base material having a first surface exposed to an atmosphere containing hydrogen and a second surface exposed to an atmosphere containing oxygen; and a hydrogen permeation inhibition and protection coating provided on the first surface of the metal base material. The metal component for electrochemical stack in the embodiment can suppress metallic corrosion also in the case where one side is in contact with air and the other side is in contact with an atmosphere containing hydrogen.

摘要： Provided is a protective-layer-coated-interconnector, a cell stack, and a fuel cell. A component (particularly Cr) of the 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 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 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 oxide containing: at least one element selected from the group consisting of Al, Ti, Cr, Fe, Ni, Cu, and Zn; and a Co element.-
