| Outline of Final Research Achievements |
A novel hydrocarbon ionomer membranes containing no fluorine atoms have been designed and synthesized. The membrane exhibited high proton conductivity and chemical stability, similar to or even better than those of the existing perfluorinated ionomer membranes. In addition, introducing a small portion of fluorinated aliphatic groups into hydrocarbon ionomer membranes was found to be effective in improving interfacial problems between the membranes and catalyst layers. With these ionomer membranes, high fuel cell performance was obtained.
