Abstract

The present invention provides an ion conducting matrix comprising: (i) 5 to 60% by volume of an inorganic powder having a good aqueous electrolyte absorption capacity; (ii) 5 to 50% by volume of a polymeric binder that is chemically compatible with an aqueous electrolyte; and (iii) 10 to 90% by volume of an aqueous electrolyte, wherein the inorganic powder comprises essentially sub-micron particles. The present invention further provides a membrane being a film made of the matrix of the invention and a composite electrode comprising 10 to 70% by volume of the matrix of the invention.
