Title:

Document Type and Number:

WIPO Patent Application WO/2021/054253

Kind Code:

A1

Abstract:

A composite electrolyte membrane with a composite layer in which a hydrocarbon polymer electrolyte has been combined with a porous fluorine-containing polymer base material, wherein the fractal dimension D representing the distribution of the hydrocarbon polymer electrolyte and the porous fluorine-containing polymer base material in the composite layer is at least 1.7.　The purpose of the present invention is to achieve high proton conduction ability and high mechanical durability in a composite electrolyte membrane comprising a hydrocarbon polymer electrolyte and a porous fluorine-containing polymer base material.
