A joint research team, including Professor Jong-hoon Joo from School of Environment and

Energy Engineering at Gwangju Institute of Science and Technology (GIST), Professor Jongseop

Hong from Yonsei University, and Dr. Tae-ho Shin from the Korea Institute of Ceramic

Engineering and Technology, has developed a manufacturing technology for solid oxide fuel

cells that operate at temperatures exceeding 900°C within just three seconds.

Solid oxide fuel cell, made of a ceramic material, is vulnerable to thermal shock due to its

low thermal conductivity and high elastic modulus. Additionally, the performance is unstable

in rapid thermal cycling.

The research team designed the electrolyte material and thickness characteristics of the

solid oxide fuel cell to enhance its resistance to high thermal shock. They implemented a

mechanical design to ensure greater flexibility compared to existing models. The ceramicbased

solid oxide fuel cell was manufactured based on this stability functioning without

breaking under rapid temperature changes during thermal stress simulations. The newly

developed solid oxide fuel cells reached temperatures above 900°C within three seconds

without cracking or breaking and maintained high stability throughout more than 100 thermal

shock cycles
