Fuel Cell Innovation By UNIST Researchers

Research team of Ulsan National Institute of Science and Technology (UNIST), Georgia Institute of Technology, and Dong-Eui University developed a novel cathode material which has outstanding performance and robust reliability even at the intermediate temperature range.
…
A UNIST research team tried to co-dope Sr and Fe and succeeded in yielding remarkable out-performance to present materials at lower operating temperature. The optimized composition has facilitated excellent oxygen reduction reaction and the novel structure has created pore channels that dramatically enhance oxygen ion diffusion and surface oxygen exchange while maintaining excellent compatibility and stability under operating conditions.
“The hardest part of this research was finding optimum composition of Sr and Fe for the best performance and robustness,” said Prof. Kim. “Previously various researches trying to dope Sr to perovskite structure had been made by many other groups. But none of them was successful for the better performance at the low operating temperature.”
The new material developed by the UNIST research team led by Prof. Guntae Kim, could be used at significantly low temperature SOFC with higher efficiency and solid reliability than the previously reported materials.
