ION CONDUCTOR

WIPO Patent Application WO/2007/135944

A1

Disclosed is an ion conductor which is composed of an inorganic porous film wherein an ionic liquid is held in fine pores. Conventional ion conductors involve such a problem that the ion conductivity is not improved when compared with that of an ionic liquid by itself. The problem is solved by an ion conductor (10) comprising an inorganic porous film (1) having a plurality of fine pores (1a) whose surfaces are bonded with a plurality of proton-donating functional groups (1b), and an ionic liquid (2) held in the fine pores of the inorganic porous film. This ion conductor is improved in the ion conductivity when compared with the ionic liquid by itself, while having high heat resistance. In addition, this ion conductor can be produced at low cost, and is able to suppress swelling upon water absorption.
