Embodiment 1
[0028] refer to figure 1 and figure 2 Shown is a schematic structural view and a schematic cross-sectional view of Embodiment 1 of a battery unit for a solid oxide fuel cell, which includes a circular box body 100 and battery sheets (not shown in the figure), and the circular box body consists of a box Bottom and box cover are composed, and this box cover has certain depth, and has edge, forms the box body 100 that has inner cavity by edge and box bottom sealing together, and one surface 110 of box body 100 has opening 120, in this In an embodiment, the surface with the opening 120 is the surface where the bottom of the box is located. Of course, the configuration of the box body 100 here is only an example, and those skilled in the art can use other methods and structures to form a circular box body with an inner cavity. The use of circular boxes here is to consider that when the battery cells are placed in the reaction furnace, the circular distribution has better thermal...
Embodiment 2
[0034] refer to Figure 3-Figure 5 , the difference between Embodiment 2 and Embodiment 1 is that, on the surface 110 of the box body sealed with battery slices, there are sinusoidal corrugations 150, and the corrugations extend along the direction of the center of the box body to the outer edge of the box body, that is to say , the surface of the box body undulates as sinusoidal corrugations along the direction from the center of the circle to the outer edge of the box, and a set of sinusoidal corrugations can be arranged at intervals of a certain radius, and each set of sinusoidal corrugations can include one or more sinusoidal waves.
[0035] The thermal stress is dispersed through the design of the sinusoidal waveform, thereby reducing the influence of the thermal stress of the battery box, combined with the above-mentioned thermal annealing process used in the preparation of the stainless steel alloy box, the influence of thermal stress on the battery unit can be better re...
