PROBLEM TO BE SOLVED : To provide an inter-connector which has a thermal expansion coefficient agreeing with its ceramic structural component, high dimensional stability, high anti-etching properties relative to both of a reduced medium and an oxide medium, high electrical conductivities obtained in contacting surface regions to an anode and a cathode, and a high unpenetrating property relative to gases, and is manufactured at a low cost, and to provide a method for manufacturing the inter-connector, and further, to provide a high-temperature solid electrolyte fuel cell having the inter-connector.
SOLUTION : The inter-connector for high-temperature solid electrolyte fuel cells includes sintered holes, and is constituted of Cr of not lower than 90 wt.%, and of Fe of 3-8 wt.%, and further, optionally of a sintered chrome alloy of 0.001-2 wt.% which contains one or more elements selected from the rare earth metal group. The sintered chrome alloy contains 0.1-2 wt.% of Al, and the sintered holes are filled with an oxide compound containing Al and Cr, at least partially.
