Embodiment 1
[0076] see figure 1 As shown, the sintered flat tube porous ceramic support body, the thickness of the flat tube is 0.8cm, the length and width of the upper and lower plane areas are: 15cm×5cm, the metal foil is fixed on the side and top surface of the ceramic support body, and the two ends of the metal foil are 1cm It is a non-porous area, and the middle 13cm is a porous area. The Ni / GDC anode was prepared by atmospheric plasma spraying on the porous area of the metal foil, covering the porous area, the ScSZ electrolyte was prepared by atmospheric plasma spraying, the anode was completely wrapped, and the LSCF cathode was prepared on the electrolyte by atmospheric plasma spraying to complete the single cell preparation.
[0077] Explanation: The side and top surfaces in this embodiment refer to the side with the fuel gas inlet and outlet as the bottom surface, and the other surfaces as the side and top surfaces. The reason for this name is that when the solid oxide fuel ce...
Embodiment 2
[0079] Sintered flat tube porous ceramic support body, the thickness of the flat tube is 1.2cm, the length and width of the upper and lower plane areas are: 25cm×6cm, the metal foil is fixed on the side and top surface of the ceramic support body, and the 1cm at both ends of the metal foil is non-porous area, the middle 23cm is a porous area. Atmospheric plasma spraying Ni / GDC hydrogen electrode wraps the porous region in the middle, atmospheric plasma spraying and densification process prepares BZCY electrolyte-wrapped hydrogen electrode and all exposed porous metal supports, and prepares spinel Mn1 on the uncovered metal foil on the electrolyte side. 5Co1.5O3 protection, cast LSM / LSCF oxygen electrodes on the two planes of the flat tube respectively, and prepare an electrolytic cell after sintering, and the prepared electrolytic cell shows a high hydrogen production rate.
Embodiment 3
[0081] Sintered flat tube porous ceramic support body, the thickness of the flat tube is 2cm, the length and width of the upper and lower plane areas are: 50cm×8cm, the metal foil is bonded to the side and top surface of the ceramic support body, and the 1cm at both ends is a dense area, and the middle 48cm is the porous area. The Ni / GDC anode was prepared by atmospheric plasma spraying method on the porous area of the metal support, covering the porous area, the ScSZ electrolyte was prepared by vacuum plasma spraying, and the anode was completely wrapped, and the LSCF cathode was prepared on the electrolyte by atmospheric plasma spraying, and two porous metal sheets were Contact the cathodes on both sides of the flat tube through the elastic force to derive the current on the cathode side to complete the preparation of the single cell. Single cell expresses good voltage and power output.
