Problems solved by technology

However, this structure uses the central conductive rod to fix the single cell, which reduces the mass transfer efficiency, so the battery output performance is low
In addition, in the process of assembling a single battery, certain technical means must be used for bonding, fixing, and sealing to form a stack. These technologies are time-consuming, laborious, costly, unstable in batch performance, and highly dependent on labor, which is not conducive to solid oxidation. industrialization of battery
When this technology is used in electrolytic cell stacks, the electrodes are easily detached and delaminated due to the drive of high temperature, high pressure and high current, which is not conducive to the development of electrolytic cells.
[0005] Chinese patent CN103349918A and Chinese patent CN101456744 respectively disclose methods for preparing honeycomb-type inorganic membranes, but the prepared honeycomb-type inorganic membranes are mainly parallel membrane components of multiple microtubes processed by extrusion molding technology in one step, because the walls of the channels They are connected to each other and cannot directly contact the external medium. The mass transfer between each honeycomb channel of this honeycomb multi-channel inorganic membrane and the outside world is severely limited, and it can only rely on the porous properties of the honeycomb wall to exchange materials with the outside world.
Three-dimensional printing technology can be used to prepare plastic profiles, metal profiles and ceramic profiles, but the real industrial application has not yet begun, especially in the field of preparation of solid oxide fuel cells has not received attention
[0007] At present, there is no report on the method of three-dimensional printing of the electrolyte support body of the honeycomb electrolytic cell with three-dimensional channels
