The present application provides an ionomer and a preparation method therefor, a membrane electrode, and a fuel cell. The structure of the ionomer comprises anions, and the polarizability of the anions is greater than or equal to 3.5x10-24 cm3. In embodiments of the present application, the polarizability of the anions represents the level of difficulty of an electron cloud of the anions in producing an induced dipole under the action of an external electric field. The higher the polarizability, the more easily the electron cloud of the anions generates stronger induced dipole interaction with polar alcohol molecules, thereby enhancing the solvation effect. In the embodiments of the present application, the polarizability of the anions is greater than or equal to 3.5×10-24 cm3. The anions have relatively high polarizability, and can form relatively strong induced dipole interaction with alcohol solvent molecules. Such interaction helps break the cohesion between ionomer molecules, making it easier for the ionomer molecules to disperse into a solvent, thereby improving the solubility of the ionomer in an alcohol solvent.
