Patent number: 8603934Abstract: A carbon nanosphere has at least one opening. The carbon nanosphere is obtained by preparing a carbon nanosphere and treating it with an acid to form the opening. The carbon nanosphere with at least one opening has higher utilization of a surface area and electrical conductivity and lower mass transfer resistance than a conventional carbon nanotube, thus allowing for higher current density and cell voltage with a smaller amount of metal catalyst per unit area of a fuel cell electrode.Type: GrantFiled: April 10, 2012Date of Patent: December 10, 2013Assignee: Samsung SDI Co., Ltd.Inventors: Hyuk Chang, Chan-Ho Pak, Jian Nong Wang
