Pr2O2SO4-La0.6Sr0.4Co0.2Fe0.8O3−δ: a new category of composite cathode for intermediate temperature-solid oxide fuel cells

A new category of composite cathode for solid oxide fuel cells is investigated, containing an oxysulphate oxygen storage material. A stable composite Pr 2 O 2 SO 4 -La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3− δ is formed, providing significant improvement in the total polarization resistance, predominantly due...

Description
Summary:A new category of composite cathode for solid oxide fuel cells is investigated, containing an oxysulphate oxygen storage material. A stable composite Pr 2 O 2 SO 4 -La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3− 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.
