NOVELTY - A anode/electrolytic half cell preparing method involves preparing fuel battery grads anode of nickel, sintering and mixing with iron oxide powder and ceramic powder II, uniformly mixing to obtain iron-rich pole mixed powder D, mixing iron oxide powder and ceramic powder II to obtain the iron-rich pole mixed powder F. The obtained gradient nickel and iron rich anode body is put into muffle furnace, to obtain the gradient nickel and iron rich anode support. The obtained support electrolyte membrane green body is placed into a muffle furnace, followed by cooling.    USE - Method for preparing anode/electrolytic half cell for solid oxide fuel battery.    DETAILED DESCRIPTION - A anode/electrolytic half cell preparing method involves preparing fuel battery grads anode of nickel by mixing nickel oxide powder and ceramic powder according to mass ratio of 5: (4-6) and uniformly mixing to obtain mixed powder A, and mixing nickel oxide powder and ceramic powder according to the weight ratio of 6-3:(5), uniformly mixing to obtain mixed powder B, and mixing nickel oxide powder and ceramic powder at mass ratio of 7: (2-4) to obtain the mixed powder C, mixing powder A, powder B and powder C, adding mixed powder A with pore-forming agent, and adding mixed powder B, to the mixed powder C with mass ratio of (8 to 12): 100, placing mixed powder into a mold, at pressure of 130 MPa, molding to obtain the gradient Ni anode blank, followed by sintering and mixing with iron oxide powder and ceramic powder II, uniformly mixing to obtain iron-rich pole mixed powder D, mixing iron oxide powder and ceramic powder II according to mass ratio of 6: (3-5) to obtain the iron -rich pole mixed powder F, mixing powder D, and powder E, dry pressing, molding under pressure of 240-280 MPa, to obtain the gradient nickel and iron rich anode body. The obtained gradient nickel and iron rich anode body is put into muffle furnace, at 1000-1400 degrees C, sintered for 1-4 hours to obtain the gradient nickel and iron rich anode support having thickness of 150 mu m and 600 mu m. Titanium dioxide nano-membrane is prepared by mixing terpineol, ethyl cellulose and vegetable oil and uniformly mixing to obtain electrolyte slurry, fixing the obtained gradient nickel and iron rich anode supporting body with a spin coater to a frame, one side of the Fe layer face upwards, setting the spin coater rotating speed at 4000 rpm for 1-5 minutes, obtaining the anode support electrolyte membrane green body. The obtained support electrolyte membrane green body is placed into a muffle furnace to sinter, followed by raising the temperature from room temperature along with the furnace naturally heating to 300 degrees C, raising the temperature to 500 degrees C, increasing temperature speed to 500 degrees C/4 hours, raising the temperature to 1400 degrees C for 3-5 hours, cooling at speed of 500 degrees C/4 hours, cooling speed of 400 degrees C /3 hours, to obtain finished product.
