Title:
ELECTROLYTIC MEMBRANE, USAGE THEREOF, AND BATTERY INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2009283468
Kind Code:
A
Abstract:
To provide an electrolytic membrane having further high ion conductivity, a usage thereof, and a fuel cell including the membrane.
The electrolytic membrane includes an ion-conducting polymer which is fixed in pores of a porous polyalkene membrane stretched in at least one direction, wherein the polyalkene membrane has a porosity of 30-90% and a mean pore diameter of 0.1 to 5.0 m. The electrolytic membrane has ion conductivity higher than a known membrane which is smaller in pore size than the electrolytic membrane and equivalent in thickness, porosity and strength thereto, and is suitable for use in solid-polymer fuel cells and batteries.
