Improved membrane-electrode assemblies and long-life fuel cells |
abstract |
High molecular weight polymer obtainable by a process involving free-radically polymerizing a composition which comprises, based on its overall weight, at least 80.0% by weight of ethylenically unsaturated compounds, characterized in that the composition comprises at least one monomer containing phosphonic acid groups and/or sulfonic acid groups. The polymer has a weight-average degree of polymerization of more than 300 and on account of its physical and chemical properties is suitable in particular for polymer-electrolyte membranes (PEM) in PEM fuel cells. |
