Abstract
Improved additives can be used to prepare polymer electrolyte for membrane electrode assemblies in polymer electrolyte fuel cells. Use of these improved additives can not only improve durability and performance, but can also provide a marked performance improvement during initial conditioning of the fuel cells. The additives are chemical complexes comprising certain metal and organic ligand components.
