Patent number: 7160968Abstract: The invention relates to solid polyelectrolyte membranes and processes for their production. As solid polyelectrolyte materials, there have been known fluoropolymers which have perfluoroskeletons and side chains bearing sulfonic acid groups and heat-resistant resins which have hydrocarbon skeletons and contain alkylsulfonic acid or alkylphosphoric acid groups introduced thereto. The fluoropolymers are excellent in heat resistance and chemical resistance but have the problem of being expensive, while the heat-resistant resins have the problem of being poor in chemical resistance. Further, solid polyelectrolyte materials having higher electric conductivities have been desired.Type: GrantFiled: October 19, 2001Date of Patent: January 9, 2007Assignee: Canon Kabushiki KaishaInventors: Iko Ito, Masahiro Rikukawa
