OH- CONDUCTOR AND PROCESS FOR PRODUCING THE OH- CONDUCTOR

摘要

Disclosed is a novel OH- conductor comprising an anion exchange polymer. The anion exchange polymer comprises at least unfreezable water among free water, bound water, and unfreezable water. The content of the free water is in the range of not more than 5 mol per mol of the functional group, the content of the bound water is in the range of not more than 1 mol per mol of the functional group, and the content of the unfreezable water is in the range of 0.1 to 10 mol per mol of the functional group. The OH- conductor comprises an anion exchange polymer filled into pores in a porous body. The anion exchange polymer preferably comprises an amidated polysulfone. The porous body preferably is formed of a porous film of a heat resistant crosslinked polyethylene. The ion conductivity of the OH- conductor is preferably in the range of not less than 0.0001 S/cm.
