摘要： There are disclosed a method for preparation of the solid oxide fuel cell single cell and a single cell with nano (micro) meso porous cathode electrode working effectively from 723 to 1073 K. The cathode electrode possesses very large surface area (10-500 m2 g'1) with the hierarchical nano (micro) mesoporous structure, very high catalytic activity and very low oxygen electroreduction activation energy varying from 0.3-0.8 eV at -0.2...0 V cathode electrode potential versus porous Pt | O2 reference electrode in air.
