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.

该方法首先将聚醚醚酮加入浓硫酸中进行磺化反应得到磺化聚醚醚酮；然后将磺化聚醚醚酮溶于有机溶剂中，加入N，N′-羰基二咪唑搅拌1～3小时后加入偶联剂搅拌反应1.5～4小时，再加入无机交联剂在50～80℃下反应，然后加入质子导体继续在此温度下反应得到磺化聚醚醚酮/无机交联剂/质子导体的混合溶液；最后将磺化聚醚醚酮/无机交联剂/质子导体的混合物溶液成膜，干燥，脱膜即得到所述的直接甲醇燃料电池用质子交换膜。
