Evaluation of cation migration in lanthanum strontium cobalt ferrite solid oxide fuel cell cathodes via in-operando X-ray diffraction

Anode-supported SOFC button cells with LSCF-6428 cathodes were operated at various temperatures under constant current conditions for hundreds of hours in dry or humid (∼3% water) cathode air while continuously collecting 1 hour XRD scans throughout the test duration. Additionally, one cell in dry a...
