PROTON CONDUCTOR AND FUEL CELL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a proton conductor capable of attaining proton conductivity of 10<-2> S cm<-1> in a dry condition, that is, in a non-humidity condition at 100 deg.C or more and to provide a polymer solid electrolyte fuel cell using the proton conductor as an electrolyte. SOLUTION: The electrolyte prepared by combining ionic liquid and Bronsted- Lowry acid serving as a proton donor together into a complex shows nonaqueous proton conductivity at 100 deg.C or more. In this way, a temperature of the solid polymer fuel cell PEFC 35 is increased and cold can be supplied with it is connected to an absorption-refrigerator 40, and heat for generating steam to be supplied to a reformer 31 can be obtained. Consequently, system efficiency can be improved.
