Title:
HIGHLY PROTON-CONDUCTIVE ELECTROLYTE
Document Type and Number:
Japanese Patent JP2001302721
Kind Code:
A
Abstract:
To obtain a highly proton-conductive electrolyte having high ion exchange capacity and a sufficient degree of dissociation in a low-humidity environment while exhibiting practical strength.
A superacid group is incorporated into a hydrocarbyl polymer in an amount of at least 1.20 milliequivalent/g in terms of the ion exchange capacity. As the superacid group, is preferably employed a fluorine-containing sulfonic acid group or a fluorine-containing sulfonimide group having a structure consisting of a sulfonic or sulfonimide group having an adjacent electron- withdrawing fluorocarbon. Further, as the hydrocarbyl polymer, is preferably employed a graft copolymer comprising a C-F bond-containing main chain and a side chain grafted thereto.
