The method comprises the steps of: providing an SOFC comprising an anodic side comprising a solid gas-permeable anode, a gas inlet and a gas outlet, a cathodic side comprising a solid gas-permeable cathode and a gas inlet and a gas outlet, and a fully dense solid electrolyte, separating the cathodic side from the anodic side; introducing an oxygen-containing gas in the inlet of the cathodic side of the SOFC; introducing an ammonia-containing gas stream in the inlet of the anodic side of the SOFC; collecting nitric oxide at the outlet of the anodic side and collecting a current flowing between the anodic side and the cathodic side. The cathode comprises a material suitable for reducing the oxygen in the oxygen-containing gas and the anode comprises a composition A 1-X A' X B 1-Y B' Y O 3-δ , wherein A is selected from the group consisting of La, Y, Sm, Pr, Nd and Gd, A' is selected from the group consisting of Ca, Sr and Ba, B and B' are each independently selected from the group consisting of Co, Fe, Mn, Cr and V or mixtures thereof, X ranges from 0.05 to 0.6 and in particular from 0.1 to 0.4, Y ranges from 0 to 1 and δ ranges from 0.025 to 0.3 The present disclosure further relates to an SOFC and stack thereof for performing the method of the disclosure, to a method for producing nitric acid and to a system thereof, and to the use of the anode in the methods and SOFC and stack thereof.

摘要： The present invention provides a catalyst for production of nitric oxide from ammonia and oxygen. The catalyst has the composition A((n+1)−x)BxC(n(1−y))DnyO(3n+1)+d, wherein A is a lanthanide (La, Gd, Nd, Sm) or yttrium, B is an alkaline-earth cation (Ca, Sr or Ba), C is Fe and D is Cr, Mn, Ni, Ce, Ti, Co or Mg, wherein A, B, C and D are selected independent of each other. The catalyst has a high selectivity towards nitric oxide and a low ignition temperature in the reactor. Further the present invention relates to a method for the production of gas comprising nitric oxide by the catalyst of the present invention. The produced gas has a very low content of nitrous oxide.
