Dr. Ho-Il Ji, Dr. Jong-Ho Lee, and Dr. Hyungmook Kang's research team at the Energy Materials Research Center, Korea Institute of Science and Technology announced that they have increased the possibility of commercialization by identifying this electrolyte sintering mechanism: a next-generation high-efficiency ceramic cell that had not previously been identified.The research team designed and conducted various model experiments based on the fact that the transient phase generated on the electrode during the electrolyte-electrode sintering process affects the densification of the electrolyte. They discovered for the first time that supplying the electrolyte with a small amount of gaseous sintering aid material from the transient phase promotes sintering of the electrolyte. Gaseous sintering aids are extremely rare and technically difficult to observe; therefore, the hypothesis that the densification of the electrolyte in prometric ton ceramic cells is caused by vaporized sintering aids has never been proposed. The research team verified the gaseous sintering aid using computational science and confirmed that the reaction did not impair the unique electrical properties of the electrolyte. Thus, the design of the core manufacturing process of prometric ton ceramic cells is expected to be possible.Through this research, we have come one step closer to developing the core manufacturing process for prometric tonic ceramic cells. We plan to conduct research on the manufacturing process of large-area, high-efficiency prometric ton ceramic cells in the future. If large-area technology is successfully developed, it will be possible to produce pink hydrogen in connection with next-generation nuclear technology as well as green hydrogen in connection with renewable energy, which will lead to the commercialization of ceramic cells and accelerate the realization of the hydrogen economy, says Dr JiGreen hydrogen production technology is absolutely necessary to finally realize the hydrogen economy because unlike gray hydrogen, green hydrogen does not generate large amounts of carbon dioxide in the production process. Green hydrogen production technology based on Solid Oxide Electrolysis Cells, which produce hydrogen from water using renewable energy, has recently attracted attention because it does not generate pollutants. Among these technologies, high-temperature SOECs have the advantage of excellent efficiency and production speed.The prometric tonic ceramic cell is a high-temperature SOEC technology that utilizes a prometric ton ceramic electrolyte to transfer hydrogen ions within material. These cells also use a technology that can reduce operating temperatures from 700 degree Celsius or more to 500 degree Celsius or less, thereby reducing system size and price and improving long-term operation reliability by delaying deterioration. However, it has been difficult to enter the commercialization stage because the key mechanism responsible for sintering prometric tonic ceramic electrolytes at relatively low temperatures during the cell manufacturing process has not been specifically identified.
