Novel ReBaCo1.5Mn0.5O5+δ (Re: La, Pr, Nd, Sm, Gd and Y) perovskite oxide: influence of manganese doping on the crystal structure, oxygen nonstoichiometry, thermal expansion, transport properties, and application as a cathode material in solid oxide fuel cells

Introduction of Mn, on the order of 0.5 in ReBaCo_1.5Mn_0.5O_5+δ, allows to develop a very good cathode material for SOFCs, as shown for Re = Nd.
