Abstract
A proton conductor, a method for manufacturing the same, and an electrochemical device using the proton conductor are provided. The proton conductor includes a carbon derivative which has a carbon material selected from the group consisting of a fullerene molecule, a cluster consisting essentially of carbon, a fiber-shaped carbon anPlease do not hesitate to contact us with any questions d a tube-regarding this matter shaped carbon, and mixtures thereof, and at least a proton dissociative group, the proton dissociative group being bonded to the carbon material via a cyclic structure of tricyclic or more. The method includes the steps of obtaining the carbon derivative, hydrolyzing the derivative with alkali hydroxide, subjecting the hydrolyzed product to ion exchange, and forming a group with proton-dissociating properties.
