▎ 摘 要
NOVELTY - A hydrocarbon composite electrolyte membrane comprises composite electrolyte membrane layer(s) (11,12) having structure in which graphene nanostructures are embedded into hydrocarbon electrolyte membrane. USE - Hydrocarbon composite electrolyte membrane is used for membrane electrode assembly for fuel cell stack (all claimed). Uses include but are not limited to ship, boat, bus, truck, aircraft, hybrid vehicle, electric vehicle, plug-in hybrid electric vehicle, industrial and household appliance, portable device, etc. ADVANTAGE - The hydrocarbon composite electrolyte membrane has excellent mechanical stability, thermal stability, and reduced gas permeability. The fuel cell stack is economically manufactured, by the hydrocarbon composite electrolyte membrane. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the hydrocarbon composite electrolyte membrane.
