Abstract: | High-temperature oxidation-resistant alloys are currently considered as a candidate material for construction of interconnects
in intermediate-temperature solid oxide fuel cells. Among these alloys, however, different groups of alloys demonstrate different
advantages and disadvantages, and few, if any, can completely satisfy the stringent requirements for the application. To integrate
the advantages and avoid the disadvantages of different groups of alloys, cladding has been proposed as one approach in fabricating
metallic layered interconnect structures. To examine the feasibility of this approach, the austenitic Ni-base alloy Haynes
230 and the ferritic stainless steel AL 453 were selected as examples and manufactured into a clad metal. Its suitability
as an interconnect construction material was investigated. This paper provides a brief overview of the cladding approach and
discusses the viability of this technology to fabricate the metallic layered-structure interconnects.
This paper was presented at the ASM Materials Solutions Conference & Show held October 18–21, 2004 in Columbus, OH. |
