Integrated Cr and S poisoning of a LaSrCoFeO (LSCF) cathode for solid oxide fuel cells.

Strontium segregation in a LaSrCoFeO (LSCF) electrode reacts with Cr and S in a solid oxide fuel cell (SOFC), which can cause cell performance deterioration. Integrated Cr and S poisoning for LSCF cathodes of SOFC was studied at 800 °C of 200 mA cm (cathodic) for 20 h. After polarization in Cr and S at 800 °C for 20 h, polarization and ohmic resistances for LSCF were 2.
