Problems solved by technology

When the airway wall and airway support are all directly connected to the electrolyte, the dimensional changes of the airway wall, airway support, airway filler and electrolyte must be Basically consistent, to ensure the integrity of the battery structure, which is usually difficult to achieve, so it is difficult to avoid stress inside the battery
In general, the airway wall, airway stent, and electrolyte are composed of dense materials with similar or identical compositions, and the internally accumulated stress is difficult to release, which increases the risk of maintaining the integrity of the battery structure and reduces the yield of the battery

Abstract

The invention relates to the field of electrochemistry, and discloses a flat tube solid oxide battery structure for improving yield and single battery power and a preparation method thereof. The structure comprises multiple pairs of electrodes; an isolation structure comprises a first electrolyte, a second electrolyte, a two-surface air passage wall and a separator plate; the cross section of an integral body formed by the two-surface air passage wall and the separator plate is in H type, and the separator plate separates the air passage into an upper and a lower part; two air passages with openings at the double ends are formed; at least one air passage rack is arranged in the air passages along a vertical direction of the isolation structure, an air passage rack does not contact electrolyte and is against an inner electrode, and the air passage rack separates the air passage into several subsidiary air passages on the same horizontal surface; the electrolyte, the air passage wall, the separator plate and the air passage rack are made of the same material or materials which have similar composition. The flat tube solid oxide battery structure has higher yield during processing, and the product has higher power.

Description

technical field [0001] The invention relates to solid oxide fuel cells, solid oxide fuel electrolytic cells, new energy sources, new materials and the field of electrochemistry, in particular to a flat tube solid oxide cell structure that improves yield and single cell power. Background technique [0002] The flat tubular battery has at least one path of gas flowing through the internal air channel, which is a gas channel that is composed of the air channel wall and electrolyte and is isolated from the outside world. Such as Figure 4 Shown is the cross-sectional structure of a common flat tube battery. In order to increase the power of a single battery, the electrode area of ​​the battery must be increased, and the width of the air passage must also be increased. However, as the airway width increases, the strength of the flat tube battery decreases, the electrolyte is easily broken, and the yield of the battery preparation also decreases. [0003] For this reason, the ap...
