High-performance single-atom catalysts for high-temperature fuel cells

Platinum (Pt)-based catalysts demonstrate such excellent performance in fuel cell electrode reactions. However, at high temperatures, the Pt atoms are not stable and easily agglomerate. Therefore, Pt single-atom catalysts have been used only in low-temperature fuel cells, like polymer-electrolyte membrane fuel cells, which is used for hydrogen electric vehicles. Under these circumstances, a domestic research team have developed a catalyst that requires only a small amount of platinum for the significant improvement of performance and can operate stably at high temperatures.
