Removal of NOx with Porous Cell Stacks with La0.85Sr0.15CoxMn1-xO3+δ-Ce0.9Gd0.1O1.95 Electrodes Infiltrated with BaO
Abstract
Porous cell stacks with composite electrodes of La<sub>0.85</sub>Sr<sub>0.15</sub>Co<sub>x</sub>Mn<sub>1-x</sub>O<sub>3</sub>-Ce<sub>0.9</sub>Gd<sub>0.1</sub>O<sub>1.95</sub> were tested for activity toward selective electrochemical reduction of NO<sub>x</sub> to N<sub>2</sub> in the presence of 10% O<sub>2</sub>. The cell stacks were produced by tape casting, laminating and sintering the backbone structure followed by infiltration with BaO or La<sub>0.85</sub>Sr<sub>0.15</sub>MnO<sub>3+δ</sub>. The cell stacks were tested in an atmosphere of 1000 ppm NO or NO<sub>2</sub> + 10% O<sub>2</sub> in Ar with 10% O<sub>2</sub> in Ar as reference, and in the temperature range of 250 to 500 °C. The cell stacks were investigated electrochemically with cyclic voltammetry and polarization, and the outlet gas composition was monitored. Doping with Co increases the electrodes activity for reducing NO<sub>x</sub>, and up to 93% conversion in the presence of 10% O<sub>2</sub> at 400 °C was measured. Infiltration with BaO was necessary to achieve any formation of N<sub>2</sub>. Square wave polarization increased the activity of the electrodes achieving a current efficiency as high as 20% at 350 °C, and this indicates a problem with mass transfer. An atmosphere containing NO<sub>2</sub> also increased the activity of the electrodes, which points to a mechanism with a NO<sub>2</sub> related intermediate. © 2014 The Electrochemical Society.
