description The invention discloses a preparation method of a silver and nitrogen doped cellulose-based carbon aerogel film for a fuel cell, which comprises the following steps: preparing a mixed solution of sodium hydroxide and urea, putting cotton linter into the mixed solution, stirring at a low speed to swell, freezing, and stirring at a high speed to obtain a cellulose solution; taking the nano-silver loaded nano-cellulose to be rotationally mixed with a cellulose solution, transferring the mixed cellulose solution into a film preparation mold, quickly freezing in liquid nitrogen, and then drying by using a freeze dryer to obtain a cellulose aerogel film; placing the cellulose aerogel film in an acid solution until the cellulose aerogel film is neutral, and then freeze-drying the cellulose aerogel film under the conditions to obtain a cellulose aerogel film; and finally, placing the cellulose aerogel film in a tubular furnace, carrying out carbonization treatment in a nitrogen atmosphere, and then naturally cooling
