プロトン伝導体および電気化学デバイス

Absstract of: JP2026111861A

【課題】幅広い温度・湿度領域において高いプロトン伝導率を確保し得るプロトン伝導体を提供する。【解決手段】プロトン伝導体は、１００℃以上の環境下で使用される。プロトン伝導体は、 ポリマー化した双性イオンとホスホン酸との複合体である。これによれば、高温・低湿条件では、ホスホン酸が双性イオンによって一部アニオン化してプロトンキャリアとなる。このため、無加湿時においても、高いプロトン伝導率を得られる。また、低温・高湿条件では、ホスホン酸のみによるプロトン伝導は活性化エネルギに従って低下するが、双性イオンの持つダイポールによって水が保持される。このため、高加湿時には、ホスホン酸によって水にプロトンが供与されるため、プロトン伝導率を向上させることができる。したがって、幅広い温度・湿度領域において高いプロトン伝導率を確保することが可能となる。【選択図】図１
