Synthesis, characterization, and conductivity measurements of hybrid membranes containing a mono-lacunary heteropolyacid for PEM fuel cell applications

Hybrid inorganic/organic membranes using a lacunary heteropolyacid proton conductor, H 8SiW 11O 39, in stable polymer matrices based on polyethylene glycol were prepared by a sol–gel method. NMR and IR measurements indicate that this improved sol–gel membrane contains robust covalent bonds between t...
