電解質膜およびその製造方法
Abstract:
(EN)
Provided is an electrolyte membrane exhibiting high proton conductivity even in low humidity. The electrolyte membrane comprises a composite membrane provided with a polyolefin microporous membrane that has an average pore size of 1 to 1000 nm and a porosity of 50 to 90% and that can be impregnated with a solvent having a surface free energy of 28 mJ/m
2
or higher, and an electrolyte containing EW250-850 perfluorosulfonic acid polymer packed into the pores of the polyolefin microporous membrane, the thickness of the composite membrane being 1 to 20 μm.
(FR)
La présente invention concerne une membrane électrolytique présentant une conductivité protonique élevée même dans des conditions de faible humidité. La membrane électrolytique comprend une membrane composite pourvue d'une membrane microporeuse en polyoléfine qui a une dimension de pore moyenne de 1 à 1000 nm et une porosité de 50 à 90 % et qui peut être imprégnée d'un solvant ayant une énergie libre de surface de 28 mJ/m
2
ou plus, et un électrolyte contenant un polymère d'acide perfluorosulfonique EW250-850 condensé dans les pores de la membrane microporeuse en polyoléfine, l'épaisseur de la membrane composite étant de 1 à 20 µm.
(JA)
