Enhanced mechanisms of oxygen reduction on Pr0.4Sr0.6Co0.2Fe0.8O3-d impregnated La1-xSrxCo1-yFeyO3-d cathodes for solid oxide fuel cells

Haizhao Li et al.

Summary: This study investigates the effects of perovskite-structured Pr0.4Sr0.6Co0.2Fe0.8O3-delta (PSCF) modification on the electrochemical performance of La1-xSrxCo1-yFeyO3-delta (LSCF) cathodes using experimental and theoretical methods. The results show that PSCF modification reduces the formation energies of oxygen vacancies, lowers the adsorption energies of oxygen adsorption on the LSCF surface, and greatly decreases the dissociation barriers of oxygen molecules on the LSCF surface. These changes result in a significant improvement in the rate of oxygen reduction reaction and the activation of the LSCF surface with PSCF modification, leading to enhanced performance of the cathode.
