- W4235557499 abstract "One of the challenges to be addressed in facilitating widespread dissemination of polymer electrolyte fuel cell (PEFC) is to reduce the amount of Pt catalysts used in PEFC. The rate of oxygen reduction reaction (ORR) (O2 + 2H+ + 4e- → 2H2O) is relatively lower at Pt surface and quite a large amount of Pt catalysts is required to increase O2 reduction rate, which is a serious problem for cathode electrodes. For instance, 100g of Pt is needed for a fuel cell vehicle. Pt usage of this sort is impractical in terms of resources as well as economics. In order to ensure widespread commercialization of PEFC, the development of non-Pt catalysts is essential. The other challenge is to improve the stability of catalysts. The activity of Pt catalysts is known to be decreased by surface poisoning during long-term use. The objective of this study is to realize non-Pt catalyst with ORR activity and higher stability by using amorphous carbon (a-C) incorporating nitrogen atoms. It has been reported that carbon alloy with quinolizinium structure at graphene edges exhibited the higher ORR activity [1]. Our research group has reported that a-C including amorphous phase and nano-sized sp2 cluster could be a conductive material by incorporating nitrogen atoms. It works as an ideal polarizable electrode with higher overpotential toward water discharge and higher stability to electrochemically-induced corrosion [2]. In the study, a-C based catalysts with higher ORR activity and higher stability was tried to be realized by introducing quinolizinium structure at the sp2cluster surface in a-C." @default.
