Low-cost solid oxide electrolysis cells are prepared based on the concept of material circular economy, aiming to achieve the goal of Power-to-X and promote energy transformation and carbon emission reduction.

A closed-loop system is for the recycling process of chemicals used, enabling the recovery of materials within the process. Additionally, the SOEC single cell area developed by this technology is 100 cm2, with a hydrogen production energy consumption of 3.08 kWh/Nm3 (1.5A/cm2@1.29V), and is expected to achieve the green hydrogen goal ($1/1kgH2/10yrs) in the "Hydrogen Shot" program of the US Department of Energy.

Firstly, it can lead to job creation in various industries, such as the energy and automotive sectors. Secondly, it reduces dependence on fossil fuels, which can lower energy costs. Thirdly, it contributes to the development of circular economy, which can create new business opportunities and increase economic growth. Lastly, it enables the efficient utilization of critical metal resources, which can reduce the need for mining and lower the environmental impact of resource extraction.
