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.
本研究では,固体中の分子の運動が関与したプロトン伝導プロセスに着目し,プロトン伝導に最適な分子運動の空間を構築することで,高プロトン伝導性固体材料の開発を目指した。多孔性材料を用いたプロトン伝導体やプロトン伝導性高分子膜について,物質内部の構造・電子状態・分子運動の解析を行い,プロトン伝導メカニズム及び伝導経路を明らかにした。これらの情報を材料設計に取入れることで,高温で安定なプロトン伝導性材料の開発ができた。
