Fuel cell interconnect with metal or metal oxide contact layer

Abstract:

A method of making an interconnect for a solid oxide fuel cell stack includes providing a chromium alloy interconnect and providing a nickel mesh in contact with a fuel side of the interconnect. Formation of a chromium oxide layer is reduced or avoided in locations between the nickel mesh and the fuel side of the interconnect. A Cr--Ni alloy or a Cr--Fe--Ni alloy is located at least in the fuel side of the interconnect under the nickel mesh.
