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.
(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.
(JA) パルス幅が10−9秒以下の超短パルスレーザーが照射されて生じる繊維状フィラーが露出した多数の細孔を有することを特徴とする繊維状フィラー含有高分子フィルム又はシートからなる複合多孔質膜、及び該細孔に高分子電解質を充填した高分子電解質膜。薄膜化が可能で、強度が高く、かつ燃料ガスのクロスリーク量が少ない高耐久性無機有機複合多孔質膜、有機−有機複合多孔質膜を得ることが出来る。この複合多孔質膜を固体高分子電解質膜として用いることによって、出力電圧及び電流密度が向上された燃料電池を得ることが出来る。
