▎ 摘　　要

NOVELTY - Membrane-electrode interface bonding layer comprises a mixture layer of a carbon-based material and a perfluorine-based ionomer laminated on a perfluorinated ionomer layer. The mixture layer is formed by laminating a catalyst layer on a hydrocarbon-based polymer electrolyte membrane. The catalyst layer is selected from carbon nanofibers, carbon nano brushes, single-layer graphene, multilayer graphene and graphene oxide. USE - The membrane-electrode interface bonding layer is useful in hydrocarbon-based membrane-electrode assembly for fuel cell. ADVANTAGE - The membrane-electrode assembly has excellent interfacial resistance. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the membrane-electrode interface bonding layer for hydrocarbon-based membrane-electrode assembly for fuel cell.
