A novel inorganic proton‐conducting membrane based on highly ordered MCM‐41 mesoporous silica with phosphotungstic acid (HPW) nanoparticles assembled within is successfully fabricated by a vacuum‐assisted impregnation method (VIM). The results of HPW impregnation by VIM and a conventional method (CIM) are compared (see figure), and the performance of the membranes in fuel cells is reported.
