摘要:
A polymer for ion conductor applications includes a polymer segment having a perfluorocyclobutyl moiety and a polymer segment not having such a moiety. One of these polymer segments is sulfonated to improve ionic conductivity. Fuel cells incorporating the ion conducting polymers are provided.
摘要:
An ion conducting membrane for fuel cell applications includes an ion conducting polymer and a tin-containing compound at least partially dispersed within the ion conducting polymer. The ion conducting membranes exhibit improved performance over membranes not incorporating such tin-containing compounds.

摘要:
A sulfonated aromatic perfluorocyclobutane block copolymer comprises a hydrophobic perfluorocyclobutane ether chain segment and a hydrophilic sulfonated perfluorocyclobutane ether chain segment. The sulfonated perfluorocyclobutane copolymer may be used to make proton conductive membranes and membrane electrode assemblies in fuel cells. Processes of making the block copolymer through thermal coupling reactions are also disclosed.
