A proton-conductive composite electrolyte membrane, for a fuel cell, comprises a metal-oxide hydrate with proton conductivity and organic macromolecules in which an intermediate layer is formed between the metal-oxide hydrate and the first organic macromolecular electrolyte. The intermediate layer can enhance the adhesion at an interface between the metal-oxide hydrate and the organic macromolecule, and thereby the amount of methanol that penetrates along the interface can be reduced. Accordingly, the composite electrolyte membrane has both high proton conductivity and low methanol permeability, and a membrane electrode assembly that comprises the composite electrolyte membrane can produce a high output.
