Abstract:
There are disclosed a membrane for a fuel cell in which voids in a porous membrane are filled with a crosslinking type ion exchange resin having both cation-exchange group and anion-exchange group via a covalent bond, wherein the ion exchange resin has ion-exchange groups with either polarity more than ion-exchange groups with the opposite polarity and at least 40% of the ion-exchange groups of the opposite polarity form ion complexes with the ion-exchange groups of the major polarity, as well as a producing process therefor.
