PROBLEM TO BE SOLVED: To provide a cross-linked polyelectrolyte having excellent permanency and useful as a proton conductive membrane such as an electrolyte for primary batteries, an electrolyte for secondary batteries, a solid polyelectrolyte for fuel cells, a display element, various kinds of sensors, a signal transmission medium, a solid capacitor or an ion exchange membrane while maintaining essentially possessed high proton conductivity. SOLUTION: This cross-linked polyelectrolyte having a high cross-linking density is produced by subjecting a monomer having at least >=2 radically polymerizable groups in one molecule to a polymerizing reaction in the presence of a proton conductive polymer. |
