摘要:
Disclosed herein are an ionic conductor including a proton conductor, a process for production thereof, and an electrochemical device (such as fuel cell) with said ionic conductor, said ionic conductor being superior in ionic conductivity, water resistance, and film forming properties. The ionic conductor is formed from a polymer in which carbon clusters having ion dissociating functional groups are bonded to each other through connecting groups. The polymer is less water-soluble and more chemically stable than a derivative composed solely of carbon clusters; therefore, it permits many ion dissociating functional group to be introduced thereinto. Moreover, if ion dissociating functional groups are introduced into also the connecting group, it is possible to prevent the concentration of ion dissociating functional groups from decreasing as the result of polymerization. The polymer can be easily synthesized by simple condensation, substitution, and hydrolysis. Therefore, the process is suitable for mass production in high yields.

An ionic conductor, such as a proton conductor, a process for production thereof, and an electrochemical device, such as fuel cell, that includes the ionic conductor is provided. The ionic conductor of the present invention is formed from a polymer in which carbon clusters having ion dissociating functional groups are bonded to each other through connecting groups which can also include one or more ion dissociating functional groups. In this regard, the polymer is less water-soluble and more chemically stable than a derivative composed solely of carbon clusters, thus displaying enhanced ionic conduction properties.

摘要:
A proton conductor mainly contains a carbonaceous material derivative, such as, a fullerene derivative, a carbon cluster derivative, or a tubular carbonaceous material derivative in which groups capable of transferring protons, for example, —OH groups or —OSO3H groups are introduced to carbon atoms of the carbonaceous material derivative. The proton conductor is produced typically by compacting a powder of the carbonaceous material derivative. The proton conductor is usable, even in a dry state, in a wide temperature range including ordinary temperature. In particular, the proton conductor mainly containing the carbon cluster derivative is advantageous in increasing the strength and extending the selection range of raw materials. An electrochemical device, such as, a fuel cell, that employs the proton conductor is not limited by atmospheric conditions and can be of a small and simple construction. The proton conductor may contain a polymer in addition to the carbonaceous material derivative, which conductor can be formed, typically by extrusion molding, into a thin film having a large strength, a high gas permeation preventive ability, and a good proton conductivity.

摘要:
A charge separation heterojunction structure which uses a fullerene polymer film as a part of its constituent materials and which may be used to produce a solar cellor a light emitting diode superior in durability, physical properties of electrons and economic merits. The heterojunction structure is such a structure in which an electron-donating electrically conductive high-polymer film and an electron-accepting fullerene polymer film are layered between a pair of electrodes at least one of which is light transmitting. In forming the layers, the fullerene polymer film is identified using in particular the Raman and Nexafs methods in combination so that upper layers are formed after identifying the polymer film.

A fuel cell usable as a small-sized secondary cell such as a button type cell and a fuel cell system including the fuel cells are provided. The fuel cell has a first electrode, an electrolyte membrane, a second electrode, and a hydrogen storing material. The electrolyte membrane has polyfullerene hydroxide as a proton conductor. When a negative voltage is applied to the first electrode and a positive electrode is applied to the second electrode, protons, electrons, and oxygen are generated from water at the second electrode, and hydrogen is generated from the electrons and the protons at the first electrode. The hydrogen thus generated is stored in the hydrogen storing material, thus performing so-called charging. At the time of power generation, protons and electrons are generated, at the first electrode, from hydrogen supplied from the hydrogen storing material, and the generated protons are conducted to the second electrode via the electrolyte membrane and water is generated at the second electrode.
