[EN] Composites made of different doped cerias and (La0.8Sr0.2)(0.95)MnO3+ were studied as potential solid oxide fuel cell cathodes. Tb, Pr, Gd and Er have been introduced as ceria dopants to enhance the electrocatalytic properties of (La0.8Sr0.2)(0.95)MnO3+ composites fabricated within. Different e...
