The objective of this research is to produce novel polymer electrolyte materials and membrane electrode assemblies (MEAs) therewith for high performance polymer electrolyte fuel cells. Structural requirements have been proposed in aromatic polymer electrolytes for improving proton conducting properties at no expense of stability and gas permeability. It was found that multiblock poly (arylene ether) s containing highly dense acidic groups in hydrophilic blocks showed extremely high proton conductivity. Superior fuel cell performance was achieved with the electrolyte materials under severe operating conditions of 100℃ and 30% RH (relative humidity).
