The invention belongs to the technical field of functional polymer materials, and particularly relates to composite resin dispersion liquid as well as a preparation method and application thereof. The composite resin dispersion liquid comprises resin, an organic solvent and water, the resin is mixed resin, and the mixed resin is formed by mixing at least two of perfluorosulfonic acid resin, perfluorophosphonic acid resin or perfluorophosphonic acid-sulfonic acid copolymer resin. The composite resin dispersion liquid can be used for polytetrafluoroethylene surface hydrophilic treatment, catalyst coating, electrochemical sensor production, other fields of electrolysis devices, electrochemical devices, electrodialysis devices and the like, and other same or similar fields. The composite resin dispersion liquid is used for preparing a fuel cell catalyst layer, the problem of low proton conductivity of an existing membrane electrode under the high-temperature condition can be solved through the contained phosphoni
