Clad Metals, Roll Bonding and their Applications for SOFC Interconnects
High temperature oxidation resistant alloys are currently considered as candidate materials for construction of interconnects in intermediate temperature SOFCs. Among these alloys however, different groups of alloys demonstrate different advantages and disadvantages for the interconnect applications, and few if any can completely satisfied the stringent requirements for the applications. To integrate the advantages and avoid the disadvantages of different groups of alloys, cladding has been proposed as the approach to fabricate metallic layered interconnect structures. To examine the feasibility of this approach, the austenitic Ni-base alloy Haynes 230 and the ferritic stainless steel AL453 were selected as examples and manufactured into a clad metal. It’s suitability as interconnect construction materials were investigated. This paper will give a brief overview of the cladding approach and discuss the viability of this technology to fabricate the metallic layered-structure interconnects.
