Abstract
The invention relates to novel inorganic-organic composite membranes especially useful as ionically conducting in electrochemical devices. The composites consist of a polymeric matrix, which may or may not be an ionic conductor in its unfilled form, filled with an inorganic material having a high affinity for water, capable of exchanging cations such as protons, and preferably with a high cation mobility, either on its surface or through its bulk.
