Embodiment 1
[0022] A preparation method of a three-pole co-fired SOFC, comprising the following steps:
[0023] 1) NiO, 8YSZ, PMMA and Fe 2 o 3 Mix according to the mass ratio of 4:6:1.5:0.3, add ball milling medium for ball milling, dry at 80°C, and fully grind to make anode powder;
[0024] 2) After putting the anode powder into the mold, apply a certain pre-pressure to make the anode layer pre-flattened as the half-cell anode layer;
[0025] 3) Add 8wt% Fe to 8YSZ powder 2 o 3 Perform ball milling and mixing, and dry at 80° C. to obtain a mixed powder as an electrolyte powder raw material. Then, add 20% water of its total mass in the mixed powder. Finally, evenly cover the electrolyte raw material on the half-cell anode layer of the mold described in step 2);
[0026] 4) Put the half-cell in the mold into a press at a temperature of 120°C and a 400MPa hydraulic press, and hold the pressure for 30 minutes to obtain a half-cell green body.
[0027] 5) Take out the half-cell green ...

[0029] A kind of preparation method of the SOFC of triode co-fired, comprises the following steps:
[0030] 1) NiO, 8YSZ, PMMA and Fe 2 o 3 Mix according to the mass ratio of 4:6:1.5:0.3, add ball milling medium for ball milling, dry at 80°C, and fully grind to make anode powder;
[0031] 2) After putting the anode powder into the mold, apply a certain pre-pressure to make the anode layer pre-flattened as the half-cell anode layer;
[0032] 3) Add 4wt% Fe to 8YSZ powder 2 o 3 Perform ball milling and mixing, and dry at 80° C. to obtain a mixed powder as an electrolyte powder raw material. Then, add 20% water of its total mass in the mixed powder. Finally, evenly cover the electrolyte raw material on the half-cell anode layer of the mold described in step 2);
[0033] 4) Put the half-cell in the mold into a press at a temperature of 120°C and a 400MPa hydraulic press, and hold the pressure for 30 minutes to obtain a half-cell green body.
