Cr diffusion at the FeCr/Cr2O3 interface: A first-principles study Vrije Universiteit Brussel
Cr diffusion from matrix FeCr alloy (metallic interconnect) results in Cr poisoning of the cathode of Solid Oxide Fuel Cells, which recently became an urgent issue to be solved. The understanding of Cr diffusion at the microscopic scale at the metal/oxide interface can provide a meaningful basis for solving this problem. In this work, we systematically study the stability of the metal/oxide interfaces and Cr diffusion at the interface by ...
