発明の名称 (英語) PROTON CONDUCTOR AND FUEL BATTERY NEW
発明の概要(英語) This proton conductor comprises a complex between phosphoric acid molecules and a coordination polymer wherein metal ions and ligands are linked successively by coordinate bonds. The phosphoric acid molecules include phosphoric acid molecules that are coordinate bonded to a metal ion, and phosphoric acid molecules that are not coordinate bonded to a metal ion. This allows, in the proton conductor comprising the structure containing the phosphoric acid molecules, the ion conductivity to be increased, and further, the stability of the structure to be improved.
従来技術、競合技術の概要(英語) BACKGROUND ART
Currently, the cost of the solid polymer type fuel cell system, from the viewpoint of simplification of the system, and at the operating temperature of 100°C or more to a fuel cell operating in non-humidified conditions is demanded. Non-humidified fuel cell in order to operate, a proton conductor plays an important role. The phosphoric acid the proton is a carrier from the promising, a phosphoric acid-containing structure containing a phosphoric acid is considered to be preferred as the proton conductor.
As a phosphoric acid-containing structure, phosphoric acid and the other components of the chemical bond to form a structure (for example, phosphosilicate glass, phosphate glass, metal salt of phosphoric acid) is present, and there is a problem with water resistance, ionic conductivity is further low. In addition, the chemically stable by introducing a matrix material and a phosphoric acid, a phosphoric acid-containing structure has been proposed to generate (for example, Non-Patent Document 1, 2). Such a matrix material, the capillary phenomenon of the pores and can be used, as the material of the proton conductor is expected.
