An ionomer, a preparation method thereof, a membrane electrode, and a fuel cell are provided, where the ionomer has a structure including an anion having a polarizability greater than or equal to 3.5×10⁻24 cm3. In the embodiments of the invention, the polarizability of the anion is a measure of the ease or difficulty with which the electron cloud of the anion undergoes an induced dipole under an applied electric field. The higher the polarizability, the easier it is for the electron cloud of the anion to generate a stronger induced dipole interaction with polar alcohol molecules, thereby enhancing the solvation effect. In the embodiments of the invention, the polarizability of the anion is greater than or equal to 3.5×10⁻24 cm3, and the anion has a higher polarizability and can form a strong induced dipole interaction with alcohol solvent molecules. This interaction helps to break the cohesion between ionomer molecules, making it easier for ionomer molecules to disperse into the solvent, thereby improving the solubility of the ionomer in alcohol solvents.
