Title: (DE) ZUSAMMENGESETZTE PORÖSE MEMBRAN, VERFAHREN ZU IHRER HERSTELLUNG, FESTPOLYMER-ELEKTROLYTMEMBRAN UND BRENNSTOFFZELLE
(EN) COMPOSITE POROUS MEMBRANE, METHOD FOR PRODUCTION THEREOF, SOLID POLYMER ELECTROLYTE MEMBRANE, AND FUEL CELL
(FR) MEMBRANE POREUSE COMPOSITE, SON PROCÉDÉ DE PRODUCTION, MEMBRANE À ÉLECTROLYTE POLYMÈRE SOLIDE, ET PILE À COMBUSTIBLE
Abstract: front page image
(EN) It is intended to provide a composite porous membrane comprising a fibrous filler-containing polymer film or sheet, characterized by having a large number of pores with an exposed fibrous filler formed by irradiation with an ultra-short pulse laser with a pulse width of 10 -9 seconds or less, and to provide a polymer electrolyte membrane having the pores that are filled with a polymer electrolyte. According to the present invention, an inorganic-organic or organic-organic composite porous membrane can be obtained, which can be prepared as a thin membrane and is highly durable with high strength and a reduced cross-leak of fuel gas. This composite porous membrane can be used as a solid polymer electrolyte membrane to obtain a fuel cell improved in output voltage and electric current density.
(FR) La présente invention concerne une membrane poreuse composite comprenant une pellicule polymère contenant une charge fibreuse ou une feuille comportant de multiples pores, dans laquelle chacun des pores comporte une charge fibreuse y étant exposée et est obtenu par irradiation par un laser à impulsions ultracourtes dont la durée d’impulsion est inférieure ou égale à 10-9 secondes. La présente invention concerne également une membrane à électrolyte polymère comprenant la membrane poreuse composite, dans laquelle les pores sont remplis d'un électrolyte polymère. Cette invention permet de produire une membrane poreuse composite inorganique-organique ou organique-organique à haute durabilité qui peut être mise sous forme d'une pellicule mince, présente une forte résistance et peut réduire les fuites croisées d’un gaz combustible. Cette membrane poreuse composite, utilisée comme membrane à électrolyte polymère solide, permet d’obtenir une pile à combustible dont la densité de courant et de tension de sortie est augmentée.
