(JP10092444-A)      The composite membrane comprises a microporous polymeric sheet with pores extending through the sheet. The structure defining the pores is at least partially covered with a functional material comprising one of: (i) inorganic particulate; (ii) metal; or (iii) an organic polymer. The pores are at least partially filled with polymer electrolyte selected from: (i) a metal salt-containing polymer composition; (ii) electrolyte-containing polymer gels; or (iii) an ion-exchange resin.    Also claimed is an electrochemical reaction apparatus in which the composite membrane is used as the electrolyte.    USE -   The composite membrane is used in e.g. lithium primary or secondary cells, magnesium cells, polymer cells and fuel cells, in electrolysis, batteries, pervaporation, gas separation, dialysis, as super acid catalysts and as enzyme immobilisation media.    ADVANTAGE -   The membrane allows good ion conduction properties and has good mechanical strength and heat resistance.
