The invention discloses a high-durability fuel cell composite proton exchange membrane, a preparation method and application thereof, including a membrane matrix and a metal oxide radical quencher dispersed in the membrane matrix, and the surface of the radical quencher is Features an organic coating. Compared with the common DuPont Nafion film, the durability of the polydopamine-coated composite film is greatly improved. The invention has a simple production process, is safe, and has low cost, and can be used in the industrialized production of the composite proton exchange membrane. |
