specific Embodiment approach 1
[0016] Specific Embodiment 1: The method for preparing a solid oxide fuel cell anode / electrolyte double-layer structure by single grouting in this embodiment is realized through the following steps: 1. Preparation of slurry: mix NiO powder and solid electrolyte powder according to the mass ratio Mix at a ratio of (0.2~5):1, then add gum arabic and water, and then ball mill for 0.25~24h to obtain a slurry, wherein the mass of gum arabic is 1%~20% of the total mass of NiO powder and solid electrolyte powder , the quality of water is 0.3~5 times of the total mass of NiO powder and solid electrolyte powder, the particle size of NiO powder is 1~50 microns, and the particle size of solid electrolyte powder is 50~800nm; 2. The anode / electrolyte double layer structure Preparation: Pour the slurry obtained in step 1 into a flat-bottomed mold with only plaster at the bottom, let it stand for 5-15 hours to obtain a green body, and then place the green body at a temperature of 1000-1500 ° ...
specific Embodiment approach 2
[0019] Embodiment 2: This embodiment differs from Embodiment 1 in that the NiO powder is pre-fired at a temperature of 600-1100°C for 2-5 hours before mixing the NiO powder with the solid electrolyte powder in Step 1. Other steps and parameters are the same as those in Embodiment 1.
[0020] In this embodiment, the NiO powder is pre-fired to adjust the particle size of the NiO powder. Part of the NiO powder particles are agglomerated, and the particle size of the agglomerated particles becomes larger, so that the difference in sedimentation speed between it and the solid electrolyte powder becomes larger, which is more conducive to obtaining the composition The solid oxide fuel cell anode / electrolyte double-layer structure with more obvious double-layer structure and better performance can be obtained by high-temperature sintering of the green body with obvious distribution characteristics and good layering.
specific Embodiment approach 3
[0021] Embodiment 3: This embodiment is different from Embodiment 2 in that the NiO powder is pre-calcined at a temperature of 800-1000° C. for 3-5 hours. Other steps and parameters are the same as in the second embodiment.
