Modeling of Ni Diffusion Induced Austenite Formation in Ferritic Stainless Steel Interconnects
Abstract
Ferritic stainless steel interconnect plates are widely used in planarsolid oxide fuel cell and electrolysis cell stacks.During stack production and operation, nickel fromthe Ni/yttria stabilized zirconia fuel electrode or from the Ni contactcomponent layer diffuses into the interconnectplate, causing transformation of the ferritic phase into an austeniticphasein the interface region. This is accompanied withchanges in volume, and in mechanical and corrosion properties of theinterconnectplates. In this work, kinetic modeling of theinter-diffusion between Ni and FeCr based ferritic stainless steel wasconducted,using the CALPHAD (CALculation of PHAse Diagrams)approach with the DICTRA (DIffusion Controlled TRAnsformation) software.The kinetics of inter-diffusion and austeniteformation was explored in detail. The simulation was further validatedby comparingwith experiments. The results show that after 2000 hat 800°C Ni diffuses more than 100 μm deep into Crofer 22 APU. Alongwith the Ni diffusion, part of the ferritic steelwith 50–60 μm in thickness has transformed into the austenitic phase.Growthof the austenite phase in commercial interconnectmaterials was predicted to take place under practical stack operationconditions.
