There is described a composite material such as venting materials and vents containing said venting materials. The vents are air- or more generally gas-permeable venting composites that are oleophobic and liquid repellent.

Composite material

A solid polymer electrolyte composite for an electrochemical reaction apparatus that possesses satisfactory ion conduction properties and has excellent mechanical strength and heat resistance, is provided. The solid polymer electrolyte composite is characterized in that a solid polymer electrolyte is contained in the continuous pores of an expanded porous polytetrafluoroethylene sheet which has continuous pores and in which the inner surfaces defining the pores are covered with a functional material such as a metal oxide. An electrochemical reaction apparatus containing an electrolyte, wherein said electrochemical reaction apparatus is characterized in that the aforementioned solid polymer electrolyte composite is used as this electrolyte is also provided.

Electrochemical energy storage means

Composite film articles and assemblies that include at least one layer of expanded fluoropolymer bonded to at least one thermoplastic sheet are fabricated using a method which can adjust the gas and liquid permeability of the composite film assemblies. These composite film articles and assemblies optionally have electroactive properties and a thin porous metallic overlayer that can serve as a current collector, and can be used in electrochemical devices such as air depolarized cells.
