Study on hydrocarbon membrane electrode assemblies for high performance fuel cells

本研究的目的是为高性能聚合物电解质燃料电池生产新型聚合物电解质材料及其膜电极组件。芳香聚合物电解质的结构要求是在不牺牲稳定性和透气性的前提下提高质子导电性能。研究发现，亲水块中含有高密度酸性基团的多嵌段聚芳醚具有极高的质子导电性。电解质材料在100℃、30% RH（相对湿度）的恶劣工况下取得了优异的燃料电池性能。

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).
