The method is realized by that polyether ether ketone is added into concentrated sulfuric acid to carry out sulfonation reaction, thereby obtaining sulfonated polyether ether ketone, then the sulfonated polyether ether ketone is dissolved in organic solvent, N, N (1)-Carbonyldiimidazole is added to stir for one to three hours, coupling agent is mixed for stirring the reaction for 1.5 to 4 hours, then inorganic crosslinking agent is mixed to react under the temperature of 50 to 80 DEG C. Proton conductors are mixed to continue getting the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors under the temperature. Finally the proton exchange membrane for a direct methanol fuel cell is obtained by that the mixed solution of the sulfonated polyether ether ketone or the inorganic crosslinking agent or proton conductors is/are processed through membrane forming, drying and exuviation.
