Title: (EN) COMPOSITE POROUS MEMBRANE, METHOD FOR PRODUCING COMPOSITE POROUS MEMBRANE, SOLID POLYMER ELECTROLYTE MEMBRANE, AND FUEL CELL
(FR) MEMBRANE COMPOSITE POREUSE, METHODE DE PRODUCTION DE MEMBRANES COMPOSITES POREUSES, MEMBRANE D'ELECTROLYTE POLYMERE SOLIDE ET PILE A COMBUSTIBLE
Abstract:
(EN) Disclosed is a composite porous membrane comprising a fibrous filler- containing polymer film or sheet having multiple pores, in which each of the pores has a fibrous filler exposed thereon and is formed by irradiation with an ultra-short pulse laser having a pulse duration of 10-9 second or shorter. Also disclosed is a polymer electrolyte membrane comprising the composite porous membrane, in which the pores are filled with a polymer electrolyte. A highly durable inorganic-organic or organic-organic composite porous membrane can be produced which can be made into a thin film, has a high strength, and can reduce the crossleak amount of a fuel gas. By using the composite porous membrane as a solid polymer electrolyte membrane, a fuel cell having improved output voltage and current density can be produced.
