1. A method for making an anion electrolyte membrane, comprising:
dissolving a fluorinated poly(aryl ether) ionomer in a solvent in a protective gas, to form a ionomer solution having a mass concentration of about 5 wt % to about 20 wt %, wherein the fluorinated poly(aryl ether) ionomer has a chemical structure represented by a formula of wherein Ar is a chemical group of wherein R is independently selected from the group consisting of hydrogen, functional groups (I), (II), (III), (IV), and (V): wherein X is at least one of F−, Cl−, Br−, I−, and OH−; adding a crosslink component to the ionomer solution to dissolve the crosslink component in the ionomer solution, to achieve a transparent solution, a mass ratio of the crosslink component to the fluorinated poly(aryl ether) ionomer being about 1:100 to about 40:100; introducing an inorganic component precursor and water to the transparent solution, to form a sol-gel mixture, a mass ratio of the inorganic component precursor to the fluorinated poly(aryl ether) ionomer being about 3:100 to about 30:100, a mass ratio of the water to the inorganic component precursor being about 0.1:100 to about 10:100; mixing a crosslink catalyst with the sol-gel mixture at a temperature of about 0° C. to about 50° C., to form a membrane casting solution, a mass ratio of the crosslink catalyst to the crosslink component being about 0.5:100 to about 10:100; coating the membrane casting solution on a substrate to form a membrane, and heating the membrane in a first temperature range of about 50° C. to about 80° C. for about 3 hours to about 24 hours, following by heating the membrane in a second temperature range of about 100° C. to about 150° C. for about 8 hours to about 24 hours; and removing the membrane from the substrate. |
