NOVELTY - A composite metal-ceramic nano fiber solid oxide fuel cell anode preparing method involves mixing a solvent, a high molecular polymer, a soluble metal salt and a ceramic precursor to form a composite metal ceramic nanometer fiber spinning solution. An electrostatic spinning process is carried out. The prepared composite fiber is added in a muffle furnace for sintering to obtain a composite metal oxide-ceramic nanometer fiber. The composite metal oxide-ceramic nanometer fiber is placed in hydrogen atmosphere to obtain a composite metal-ceramic nanometer fiber anode material.    USE - Method for preparing composite metal-ceramic nano fiber solid oxide fuel cell anode.    ADVANTAGE - The method enables preparing composite metal-ceramic nano fiber solid oxide fuel cell anode with better electro-chemical performance, increased power density and low polarization resistance.    DETAILED DESCRIPTION - A composite metal-ceramic nano fiber solid oxide fuel cell anode preparing method involves mixing a solvent, a high molecular polymer, a soluble metal salt and a ceramic precursor to form a composite metal ceramic nanometer fiber spinning solution and an additive, where the soluble metal salt is acetate, copper acetate or cobalt acetate, and the ceramic precursor is SDC precursor or GDC precursor. An electrostatic spinning process is carried out to prepare a composite metal-ceramic nano fiber followed by adding the composite metal-ceramic nanometer fiber spinning solution in a micro sample injector for receiving a composite nanofiber under action of an electrostatic field, where the electro-spinning condition comprises static pressure of 10-30 kV, flow speed of 0.1-1 mL/h, distance of composite fiber is 8-20 cm, temperature of 10-30 degrees C, and humidity of 10-50 %,. The prepared composite fiber is added in a muffle furnace for sintering at70-l20 degrees C for 3 hours to obtain a composite metal oxide-ceramic nanometer fiber. The composite metal oxide-ceramic nanometer fiber is placed in hydrogen atmosphere to obtain a composite metal-ceramic nanometer fiber anode material.
