Abstract
The membrane electrode assembly (MEA) of the present invention is a fuel cell MEA including an anion exchange membrane and a catalyst layer disposed on the surface of the membrane. In the MEA, the anion exchange membrane is an anion-conducting polymer electrolyte membrane in which a graft chain having anion conducting ability is graft-polymerized on a substrate formed of a skived film of ultra-high molecular weight polyolefin. This MEA has various superior properties for achieving an improvement in the power output of an anion exchange PEFC compared to conventional MEAs.
