Title:
ION-CONDUCTIVE COMPOSITE ELECTROLYTE AND MEMBRANE-ELECTRODE ASSEMBLY USING THE SAME, ELECTROCHEMICAL APPARATUS USING THE MEMBRANE-ELECTRODE ASSEMBLY, AND METHOD FOR PRODUCING ION-CONDUCTIVE COMPOSITE ELECTROLYTE MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2011/010742
Kind Code:
A1
Abstract:
Provided are an ion-conductive composite electrolyte having improved ion conductivity, a membrane-electrode assembly and electrochemical apparatus which use the same, and a method for producing an ion-conductive composite electrolyte membrane. A proton-conductive composite electrolyte contains an electrolyte having a proton-dissociating group (-SO3H) and a compound having a Lewis acid group MXn-1, in which the Lewis acid group and proton-dissociating group interact. The compound having the Lewis acid group is a polymer containing a Lewis acid compound MXn or the Lewis acid group MXn-1. The electrolyte having the proton-dissociating group is, for instance, a fullerene derivative. The proton-conductive composite electrolyte membrane is formed using a solvent having a donor number of 25 or less, and the membrane-electrode assembly which uses the proton-conductive composite electrolyte membrane is preferably used in a fuel cell.
