Abstract Amorphous TiO2 was introduced into the anion exchange membrane (AEM) derived from vinylbenzyl chloride-divinylbenzene copolymers. The structures and morphologies were characterized by FT-IR, XRD and SEM. The properties such as ion exchange capacity, hydroxide conductivity, swelling ratio and water uptake were calculated, and the fuel cell performance was tested and compared. The results showed that the hydrophilic/hydrophobic phase separation of the AEM was improved, the water uptake of the AEM also increased from 22.5% to 40.6% and the hydroxide conductivity increased from 35 mS/cm to 43 mS/cm at 30 °C in deionized water, and the fuel cell performance was greatly enhanced under unsaturated humidification conditions.
