摘要：An anode-supported tubular solid-oxide electrolytic cell (AT-SOEC) for NO decomposition has been designed and fabricated successfully by dip-coating technique. The AT-SOEC comprised porous (La0.8Sr0.2)(0.95)MnO3 (LSM95) as anode substrate, LSM95/8 mol% yttria stabilized zirconia (8YSZ) as both anode active layer and cathode layer, and 8YSZ as electrolyte. XRD patterns demonstrated that LSM95 and 8YSZ had good phase stability at 1250 degrees C and in NO atmosphere which indicated that they were proper electrode and electrolyte materials for NO decomposition. Electrodes with graphite powder as pore former showed uniform porosity to promote gas transmission, and the electrolyte was well densified with a thickness of less than 10 mu m after sintered at 1250 degrees C. The designed AT-SOEC was proved to work effectively for decomposing NO (3500 ppm, balanced in N-2), and results indicated that the decomposition rate of NO increased with temperature and current, and the maximum NO decomposition rate (99%) was obtained at 800 degrees C.
