E. Siebert, ELECTROCATALYSIS AND MORPHOLOGY AT CATHODE MATERIALS FOR THE OXYGEN REACTION ON SOLID OXIDE IONIC CONDUCTORS, Electrochimica acta, 39(11-12), 1994, pp. 1621-1625
Electrocatalytic effects on solid oxide ionic conductors in high tempe
rature systems are discussed. The oxygen electrode reaction on a solid
electrolyte is depicted. Possible oxygen reduction pathways are revie
wed as a function of the nature of the electrode and electrolyte surfa
ce. What is meant by electrocatalysis is defined and illustrated in tw
o examples: the oxygen reduction on perovskites and on doped yttria-st
abilized zirconia.
