Abstract

The invention provides a modified solid oxide fuel cell electrode. The modified solid oxide fuel cell electrode comprises a solid oxide fuel cell electrode and modified phase nanoparticles compounded on the solid oxide fuel cell electrode, the material of the modified phase nanoparticles comprises one or more of a single metal oxide, a doped metal oxide and a perovskite type catalytic material. According to the invention, a solvothermal method is adopted for modification, in-situ growth of modified phase nanoparticles is carried out on the surface of the solid oxide fuel cell, and a modified electrode with a specific microstructure and structure is obtained. The polarization impedance of the modified electrode is obviously reduced, the output power of the cell is obviously improved, and the preparation method is simple in process, easy to operate, good in morphology controllability, low in reaction temperature and low in energy consumption, and is a preparation method of the in-situ modified solid oxide fuel cell electrode with relatively high feasibility.
