A porous electrochemical reactor, made of La0.85Sr0.15FeO3 as electrode and Ce0.9Gd0.1O1.95 as electrolyte, was studied for the electrochemical reduction of NO with Propene. In order to enhance the effect of polarization, the reactor was impregnated with Ce0.9Gd0.1O1.95, CeO2 or Ce0.8Pr0.2O2-d nanoparticles. The HC-SCR on the cells was increased on the impregnated cells, but no electrochemical enhancement of this was observed. The applied overpotential on the impregnated cells changed the oxidation reaction of NO into NO2 which is considered an intermediate in the NO reduction to nitrogen.
