要約
(EN)
Disclosed is a solid polymer electrolyte membrane for fuel cells which is characterized by being obtained by graft-polymerizing a polymerizable monomer to a resin film irradiated with a radiation in such a manner that the number of units of the graft chain is not more than 30, and then sulfonating the resulting film. Since the solid polymer electrolyte membrane produced by such a radiation graft polymerization has high ion conductivity and low methanol permeability, it is suitable as an electrolyte membrane for fuel cells, especially an electrolyte membrane for direct methanol fuel cells.
(FR)
L'invention concerne une membrane électrolyte polymère solide pour piles à combustible caractérisée en ce qu'elle est obtenue par polymérisation-greffage d'un monomère polymérisable sur une couche de résine soumise à un rayonnement, de telle façon que le nombre d'unités de la chaine greffée est inférieur ou égal à 30, suivie d'une sulfonation de la couche obtenue. Comme la membrane électrolyte polymère solide produite par une telle polymérisation-greffage sous rayonnement a une forte conductivité ionique et une faible perméabilité au méthanol, elle peut servir de membrane électrolyte pour piles à combustible, en particulier comme membrane électrolyte pour les piles à combustible à méthanol direct.

 放射線を照射した樹脂フィルムに、グラフト鎖のユニット数が30以下になるように重合性モノマーをグラフト重合させると共に、スルホン化してなることを特徴とする燃料電池用固体高分子電解質膜。  本発明の放射線グラフトにより製造された固体高分子電解質膜は、高いイオン伝導度を示し、かつメタノール透過度が低いため、燃料電池用の電解質膜、特にダイレクトメタノール型燃料電池用の電解質膜として適している。
