B-site doping of lanthanum strontium titanate for solid oxide fuel cell anodes

摘要

In this study the properties of the compounds La_(0.33)Sr_(0.67)Ti_(0.92)X_(0.08)O_(3+δ) where X = Al~(3+), Ga~(3+), Fe~(n+), Mg~(2+), Mn~(n+) and Sc~(3+), have been investigated in the search for alternative solid oxide fuel cell anodes. The choice of dopant controls the structure, redox properties, conductivity and electrocatalytic properties of the compound.
