| titleOfInvention | Flexible aerogel-based fuel cell carbon paper and preparation method thereof |
| abstract | The invention belongs to the technical field of fuel cell membrane electrodes, and provides flexible aerogel-based fuel cell carbon paper and a preparation method thereof. The method comprises the steps of taking a conductive carbon material, methyl triethoxysilane, plant fiber, ethanol, water and ammonia water as raw materials, preparing wet gel under an acidic condition, then mixing and plasticizing the wet gel with inorganic fiber, polyvinyl alcohol, a plasticizer and sodium bicarbonate to prepare a sheet, and finally drying to prepare the flexible aerogel-based fuel cell carbon paper. Compared with the traditional method, the carbon paper for the gas diffusion layer of the fuel cell prepared by the invention has the advantages of good stiffness, tensile strength and flexibility, high porosity, simple process, easy control and easy large-scale production. |
