| Outline of Final Research Achievements |
In this study, we focused on the proton conduction process involving molecular motion in solids and aimed to develop highly proton-conductive solid materials by constructing a space of optimal molecular motion for proton conduction.
For the proton-conducting polymer membranes and porous materials, the local structure, electronic state, and molecular motion were analyzed to clarify the proton conduction mechanism and conduction pathways. By incorporating the obtained information into material design, stable proton-conducting materials at high temperatures were developed.
