Interfacial long-term effects of LSCF cathodes fired at different temperatures and tested at high current densities

Probing the Transport Properties, Electrophoretic Deposition, and Electrochemical Performance of La2–xSmxCe2O7 Ceramics for IT-SOFCs

“…Furthermore, it is plausible that the cell may exhibit stability over a prolonged period of time. This particular observation bears resemblance to the findings of DiGiuseppe, 59 who documented a significant decrease in the R p of LSCF-based cathodes after a duration of 1050 h. In order to ascertain the underlying cause of this phenomenon, the DRT (DRTtools) was analyzed, which can effectively elucidate the corresponding gas reaction mechanism in electrodes and the electrolyte during the operation of SOFCs. 60,61 The DRT spectra of the LSCObased SOFC are depicted in Figure 6d.…”
