Hollow mesoporous silica microspheres are synthesized, functionalized by three different acid–base pairs, and then incorporated into a Nafion matrix to prepare novel hybrid membranes. Hydrophilic ionic channels adjusted inorganic fillers, as result, the membranes display greatly improved proton conductivity, especially under low humidity.
