Embodiment 1
[0015] NiO, YSZ, and BZY were ball-milled for 32 hours according to the mass ratio of 45:25:30, mixed evenly, tape-casted, and sintered at 960°C for 6 hours to obtain a 360-micron-thick anode green body. The mixed slurry of YSZ and BZY was drip-coated on the anode ceramic green body with a mass ratio of 1:1. After drying for 10 hours, it was sintered at 1290°C for 8 hours to obtain a 20-micron YSZ (BZY) composite film with a density of 96.3%. Mix GDC and YSZ at a molar ratio of 1:0.1, add terpineol and PVB glue, the mass ratio to the mixed powder is 0.3:1:1, stir evenly and ultrasonicate for 38 hours to obtain interlayer slurry. The interlayer slurry was drip-coated on the surface of the dense YSZ (BZY) composite membrane, dried at room temperature for 8 hours, and then sintered at 1300°C for 5 hours to obtain a composite film with a porosity of 63%, a pore size of 0.12 microns to 0.50 microns, and a thickness of 3.2 microns. Porous compartment. Then apply the BCFZY cathode s...
Embodiment 2
[0017] NiO, YSZ, and BZY were ball-milled for 42 hours according to the mass ratio of 40:30:30, mixed evenly, tape-casted, and sintered at 1000°C for 5 hours to obtain a 420-micron-thick anode green body. The YSZ and BZY slurry was drip-coated on the anode ceramic green body, dried for 10 hours and then sintered at 1310° C. for 6 hours to obtain a 10-micron YSZ (BZY) composite film with a density of 98.5%. Add fish oil and PVB glue to GDC at a mass ratio of 0.3:1:1 to the mixed powder, stir evenly and ultrasonicate for 52 hours to obtain interlayer slurry. The interlayer slurry was screen-printed onto the surface of the YSZ (BZY) composite membrane, dried at room temperature for 12 hours, and then sintered at 1320°C for 6 hours to obtain a film with a porosity of 58.2%, a pore size of 0.2 microns to 2.0 microns, and a thickness of 8 microns. GDC porous barrier. Then apply the LSM cathode slurry to the interlayer, dry at room temperature, coat the LSC cathode, and sinter at 10...
Embodiment 3
[0019] NiO, YSZ, and BZY were ball-milled for 56 hours according to the mass ratio of 50:25:25, mixed evenly, tape-cast, and sintered at 960°C for 6 hours to obtain a 370-micron-thick anode green body. The YSZ and BZY composite slurry was drip-coated on the anode ceramic green body, dried for 10 hours and then sintered at 1310° C. for 7 hours to obtain an 8-micron YSZ (BZY) composite film with a density of 97.8%. Mix GDC and CMO at a molar ratio of 1:0.01, and add terpineol containing 6% ethyl cellulose, n-butanol, and the mass ratio of the mixed powder is 0.3:1:1, stir evenly and ultrasonically for 24h to obtain layer slurry. The interlayer slurry was spin-coated on the surface of the dense YSZ (BZY) composite membrane, dried at room temperature for 2 hours, and then sintered at 1320°C for 3 hours to obtain a film with a porosity of 53%, a pore size of 0.20 μm to 0.80 μm, and a thickness of 5 μm. Composite porous barrier. Then apply the BCFZY slurry to the interlayer, dry a...
