To provide the heat-meltable fluorine-containing resin fiber having excellent intermingling property and various materials for fiber products obtained therefrom. The heat-meltable fluorine-containing resin such as ETFE having a branched structure is used solely or mixed to other fiber such as an electrically conductive fiber to be formed into a non-woven fabric.

Heat-meltable fluororesin fibers

A material for electrode which is excellent in electric conductivity, gas permeability, water repellency and chemical resistance and has enhanced handling property, moldability and processability is provided. A gas diffusion electrode for a fuel battery which is obtained by using a non-woven fabric comprising a fluorine-containing resin fiber and electrically conductive fiber as a material for electrode is formed.

Material for electrode comprising a non-woven fabric composed of a fluorine-containing resin fiber

A method of laminating at least two gas permeable sheet materials includes: (1) providing at least a first gas permeable sheet material, wherein at least a portion of at least a surface region of the first sheet material is thermoplastic material; (2) providing at least a second gas permeable sheet material of polytetrafluoroethylene; (3) superposing the sheet materials; and (4) contacting the sheet materials with a heating means to heat the thermoplastic material to a temperature from 140&deg; to 230&deg; C., so as to melt the thermoplastic material and laminate the sheet materials to one another, without the application of direct pressure in the thickness direction of the sheet materials during the contacting step so as to form a gas permeable laminate.
