Abstract
An ion conducting membrane comprising dendrimeric polymers covalently linked into a network structure. The dendrimeric polymers have acid functional terminal groups and may be covalently linked via linking compounds, cross-coupling reactions, or copolymerization reactions. The ion conducting membranes may be produced by various methods and used in fuel cells.
Claims23
An ion conducting membrane comprising a plurality of dendrimers, each of the dendrimers having acid functional terminal groups, wherein the dendrimers are covalently linked and the ion conducting membrane has an acid equivalent weight between about 150 and about 500.
