Proton coherence in polymer fuel cell electrolytes

DOI

Recent studies of short side chain(SSC) polymers used in fuel cells have shown that they have higher conductivity and better structural properties than Nafion, the commercially used polymer material. These materials work by entraining water in a spongelike network created by the polymers. DINS studies on water in confined spaces have shown that the proton coherently delocalizes near the surface of the space. The short side chains change that surface in the polymers. An earlier experiment shows that a significant fraction (>.3)of the protons in Nafion are in delocalized wells. We propose to determine if this delocalization is occurring in the SSC polymer DOW 858 and in Nafion under the same conditions of hydration, and if the delocalization is correlated with the increased conductivity.
