Abstract

The invention discloses an electrolyte-supported solid oxide fuel cell with a three-dimensional topological structure based on light-curing 3D printing technology. The invention adopts light-curing 3D printing technology, which has fast printing speed, high forming precision and high printing resolution. The advantages of low surface roughness of printed products. The present invention mainly has the following five steps: preparing ceramic photocurable resin slurry; designing a three-dimensional model with a three-dimensional topological structure by using the three-period minimization surface method (TPMS); photocuring 3D printing ceramic body; degreasing the ceramic body Sintering; filling of electrode material. The electrolyte-supported solidified fuel cell with a three-dimensional topological structure greatly increases the area of ​​the electrolyte-electrode effective contact surface, improves the power density per unit volume, and has independent high-connectivity pore structures to facilitate the discharge of reaction gases. Combining the advantages of the above two aspects, the product of the invention will greatly improve the power generation efficiency of the solid oxide fuel cell.

Description

technical field [0001] The invention belongs to the technical field of solid fuel cells, and in particular relates to a solid electrolyte supported oxide fuel cell with a three-dimensional topological structure and a preparation method thereof. Background technique [0002] In my country, coal has been the main energy source for power generation for a long time. Today, coal power accounts for about 75% of China's total power generation. With the further development and utilization of other resources and the development of nuclear power, although the proportion of coal power generation has declined, it is expected that in the next five to ten years, coal power will still account for my country's total power generation energy. More than 70%. A large amount of coal-fired power generation and heat supply will bring a heavy burden on environmental protection. Dust particles, ash, and flue gas produced in the process of coal-fired power generation will pollute the air, and the w...
