The nanofiber material is fabricated by electrospinning technology, which has the controllable length and high ordered structure. The nanofiber structure has unique structural advantages for applying the electrode of Solid Oxide Fuel Cell (SOFC), which can effectively improve the performance of SOFC. The nanofiber electrode has a larger specific surface area, porosity and active sites, which is conducive to the adsorption and dissociation of oxygen, and is more conducive to the rapid conduction of ions and electrons along the fiber direction, thus more effectively promoting the oxygen reduction reaction. The combination of electrospinning technology and solution impregnation technology can construct nanofiber composite electrode with controllable structure, which has excellent catalytic performance and effectively improves the performance of SOFC at medium and low temperature. In the future, it is necessary to further study the influence of polymer and external environment on the strength of nanofibers, so as to further improve the strength of nanofibers and optimize the electrode structure.
