Pr2O2SO4–La0.6Sr0.4Co0.2Fe0.8O3−δ: a new category of composite cathode for intermediate temperature-solid oxide fuel cells
Abstract
A new category of composite cathode for solid oxide fuel cells is investigated, containing an oxysulphate oxygen storage material. A stable composite Pr2O2SO4–La0.6Sr0.4Co0.2Fe0.8O3−δ is formed, providing significant improvement in the total polarization resistance, predominantly due to improvements in the processes of interfacial charge transfer and surface exchange.
