Abstract
By virtue of graduated person’s efforts, the Electro-Catalysis Catalyst (ECC) can deal with the NOx emission without further use of reductants. For convenience concerns, we combine the idea of metal-supported solid oxide fuel cell and the idea of ECC to construct the Metal-Supported Electrochemical Double-cell Plates (MS-EDP) for the purpose of reducing costs and difficulty in manufacture process. After a series of experiments, the result shows that MS-EDP’s deNOx ability can be enhanced by the addition of Ni powders and the higher the oxygen concentration is, the better MS-EDP’s deNOx ability is. Moreover, we simulated the emission condition in factories to test the MS-EDP’s deNOx ability, and we found that MS-EDP and MS-EDP Module’s deNOx ability is better than Selective Catalytic Reduction (SCR) in low NOx concentration. This result shows the potential and feasibility of MS-EDP in dealing with the NOx emissions of factories.Furthermore, the optimum of catalyst weight for MS-EDP is 0.021 g/cm2 for both (La0.8Sr0.2)0.95CoO3-GDC and La0.6Sr0.4CoO3-GDC catalysts, and MS-EDP would show the best deNOx ability.
