The invention discloses microporous layer slurry for an air self-breathing proton exchange membrane fuel cell as well as a preparation method and application of the microporous layer slurry. The microporous layer slurry is prepared from the following raw materials: composite conductive filler, a silane coupling agent, composite resin, a dispersing agent and a water repellent agent, wherein the composite conductive filler is composed of acetylene black and multi-walled carbon nanotubes, and the multi-walled carbon nanotubes account for 50%-70% of the composite conductive filler; the composite resin is composed of epoxy resin and polyurethane, and the polyurethane accounts for 50-80% of the composite resin; during preparation, the silane coupling agent is adopted to carry out surface modification on the composite conductive filler, and then the composite conductive filler is uniformly mixed with other raw materials; the microporous layer slurry does not contain an organic solvent, and after the prepared micropo
