· Journal of the Electrochemical Society
Using cone shaped electrodes, the electrochemical reduction of nitric oxide and oxygen has been investigated by cyclic voltammetry on an oxygen overstoichiometric (La{sub 0.85}Sr{sub 0.15}MnO{sub 3+{delta}}), and an oxygen stoichiometric (La{sub 0.85}Sr{sub 0.15}CoO{sub 3{minus}{delta}}) perovskite over the temperature range 300--500 C. An oxygen ion-conducting 10% gadolinium-doped cerium oxide is used as electrolyte. It is shown that the reduction of nitric oxide proceeds rapidly on La{sub 0.85}Sr{sub 0.15}MnO{sub 3+{delta}} compared to the oxygen reduction while the oxygen reduction on La{sub 0.85}Sr{sub 0.15}CoO{sub 3{minus}{delta}} is faster than the nitric oxide reduction.
