| Outline of Final Research Achievements |
Novel organic materials with mixed-conductive were developed, and progressed research aimed at investigation the correlation between the structure and electron and ion conductivity. In particular, to ionic liquid type polymers specialized for proton conduction, they become materials that opene up the applied for ionic liquid type polymers to PEFC electrolytes, and their ripple effect is large. In this study, the proton conduction electrolyte containing ionic liquid was synthesized and mesured proton conductivity. As a result, cleary proton conductivity was confirmed in hydrogen atmosphere. Now, As a method of confurm proton conductivity, measurement system using direct current method are being established. And we are promoting research aimed at practical use under going.

| Academic Significance and Societal Importance of the Research Achievements |
発電効率、発電コストを考慮すると、固体高分子型燃料電池（PEFC）の動作温度は、150℃以上が理想である。しかしながら現在用いられている電解質は、プロトン伝導機構として水が必要なため、100℃以上の動作温度では発電性能が著しく低下する。本研究で合成した材料では、プロトン伝導に水ではなくイオン液体を用いるため、100℃以上の高温においても、発電性能が低下しない画期的なPEFCの材料としての利用が可能となりうる。
