This project aims to use defective carbon to replace expensive platinum as a catalyst for oxygen reduction reaction (ORR) in fuel cells. Defective carbons incorporating non-precious metals are better than platinum in terms of over-potential, current density and number of electron transfer. They reduce the overall fuel cell cost but their better stability and higher open voltage and power density promise huge commercial benefit. This project is expected to be important for large-scale implementation of fuel cells.

该项目旨在使用有缺陷的碳取代昂贵的铂作为燃料电池中氧还原反应（ORR）的催化剂。含有非贵金属的缺陷碳在过电位、电流密度和电子转移次数方面优于铂。它们降低了燃料电池的总成本，但它们更好的稳定性和更高的开路电压和功率密度预示着巨大的商业利益。该项目预计将对燃料电池的大规模实施具有重要意义。
