- - Interface adhesive layer of membrane-electrode for fuel cell membrane electrode assembly and fuel cell using the same

摘要

The present invention relates to a hydrocarbon-based electrolyte polymer and a gradient of a Nafion polymer composition to overcome the problem of detaching the interface during the operation of the fuel cell due to the lack of compatibility between the hydrocarbon-based electrolyte membrane and the catalyst layer containing the fluorine- Electrode interfacial adhesion layer and a membrane electrode assembly (MEA) using the membrane-electrode interfacial adhesion layer and the membrane-electrode interfacial adhesion layer for a fuel cell, the membrane-electrode interfacial adhesion layer comprising a mixture of a hydrocarbon polymer and a fluorine- In the interfacial adhesion layer, the membrane-electrode interface adhesion layer has a composition gradient of a hydrocarbon-based polymer and a fluorine-based polymer in a thickness direction, a membrane-electrode interface adhesion layer for a fuel cell, a membrane- It is about batteries.
