摘要：
The present invention provides an electrolyte membrane with high proton conductivity and low methanol permeability, a high output MEA and DMFC. The electrolyte membrane is characterized by comprising a metal oxide hydrate having proton conductivity and an organic polymer having proton conductivity. A preferable metal oxide hydrate is zirconium oxide hydrate or tungsten oxide hydrate. The composite electrolyte membrane has an ion exchange capacity of 0.75 to 1.67 meq/g as a preferable range. The composite electrolyte membrane constituted by the metal oxide hydrate and the organic polymer is provided with high proton conductivity and low methanol permeability so that MEA for DMFC with high output is provided.
