Abstract
Ligand additives having two or more coordination sites in close proximity can be used in the polymer electrolyte of membrane electrode assemblies in solid polymer electrolyte fuel cells in order to reduce the dissolution of catalyst, particularly from the cathode, and hence reduce fuel cell degradation over time.
