  "textContent": "Provided are a carbon nanosphere having at least one opening, a method of preparing the same, a carbon nanosphere- supported catalyst using the carbon nanosphere having at least one opening, and a fuel cell using the carbon nanosphere- supported catalyst. The carbon nanosphere having at least one opening is obtained by preparing a carbon nanosphere and treating it with an acid so as to form the opening. The carbon nanosphere having 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. Further, in the method of preparing the carbon nanosphere having at least one opening, the carbon nanosphere having at least one opening can be obtained in a simple and efficient manner.",
