Abstract
A proton conductor is formed of a porous body as a substrate and proton-conducting polymer covalently bonded to inner surfaces of pores of the porous body. The proton-conducting polymer comprises a main chain and a plurality of branched side chains extending radially therefrom. The branched side chains are each bonded to a proton-conducting salt at the end. The proton-conducting polymer has a substantially cylindrical structure in which the salts can be circumscribed by a virtual circle having a center on the cross-sectional center of the main chain such that a radial direction of the virtual circle is perpendicular to a longitudinal direction of the main chain. The salts are located on the peripheral wall of the substantially cylindrical structure. Protons are transferred between the adjacent salts, so that a conduction channel is formed on the peripheral wall of the cylindrical structure.
