Abstract

The description includes materials that may be useful for fuel cell applications such as in the manufacture of fuel cell electrodes, proton exchange membranes (PEM), as catalyst additives or in tie layers designed to be thermally and chemically robust while operating within a fuel cell's harsh environment at higher temperatures and to conduct protons, with significantly higher levels of bound acidic groups, while in a low hydration state. Methods of making the materials are also described.
