Notizen:
The catalytic and electrical properties of an electrochemical NOx reduction system wereinvestigated. A power above 3.5W/cm2 reduced more than 60% of NOx to N2 over the(La,Sr)CoO3-α/Ce0.9Gd0.1O1.95/Pt laminated system in a temperature range of 450°C to 650°C. O2-transportation removed the oxygen around the cathode layer through the Ce0.9Gd0.1O1.95 electrolytelayer, then NO was able to decompose to N2 at the cathode. This ceria-based system exhibitedstable NOx reduction with respect to electrical power, regardless of operating temperature
