HIGH-TEMPERATURE PROTON-EXCHANGE MEMBRANE USING IONOMETER/SOLID-MATERIAL PROTON CONDUCTOR, METHOD FOR ITS MANUFACTURE, AND FUEL CELL INCORPORATING IT

摘要

FIELD: high-temperature proton-conducting membranes for fuel cells. ^ SUBSTANCE: proposed proton-conducting polymeric membrane designed to ensure normal operation of fuel cells under high-temperature and normal-pressure conditions has sulfoalkyl and sulfoaryl groups introduced between metal phosphate layers and cation-exchange groups in side circuits; method for producing such membrane and membrane-electrode assembly using proton-exchange membrane, as well as fuel cell incorporating such membrane are given in invention specification. ^ EFFECT: improved electrochemical properties and thermal stability. ^ 10 cl, 6 dwg, 14 ex
