PROTON CONDUCTOR CONSISTING OF METAL OXIDE NANO POROUS MATERIAL, ELECTROLYTE OR PROTON CONDUCTIVE DEVICE OF FUEL CELL USING THE CONDUCTOR, AND MANUFACTURING METHOD OF THE CONDUCTOR

摘要

PPROBLEM TO BE SOLVED: To obtain (1) stable and high proton conductivity at a boiling point or more of water (100 to 160), (2) obtain stable and high proton conductivity under high humidity (70 to 100% relative humidity), and (3) obtain stable and high proton conductivity under high pressure (under steam of 1 atm. to 6 atm.) as a proton conductor composed of a metal oxide nano porous material. PSOLUTION: This is the proton conductor composed of the metal oxide nano porous material in which phosphorous pentoxide or a phosphoric acid group is provided in a micropore surface or a micropore structure of the metal oxide nano porous material of at least one component selected from titania, tin oxide, vanadium oxide, tungsten oxide, and manganese oxide.
