KAKENHI (Grants-in-Aid for Scientific Research) 1

  1. AEM型水電解反応場の物質移動設計による革新的水電解槽の創出

    Grant number:22K20479  2022.8 - 2024.3

    科学研究費助成事業  研究活動スタート支援

    Authorship:Principal investigator 

    Grant amount:\2860000 ( Direct Cost: \2200000 、 Indirect Cost:\660000 )

    再生可能エネルギーの積極導入のためには中核を担う水素製造装置、及び製造される水素に大幅なコスト低減が求められる。この要求に対し、本研究では、未実用だが高いコスト低減可能性を持つ中性pH水電解に着目し、その効率を実用レベルまで高めることを目指す。特に、水電解槽が操業される高反応速度で運転可能なアニオン交換膜(AEM)型水電解を対象とし、検討例の無い中性pH濃厚緩衝水溶液を電解質として用いることで、従来AEM型水電解の実用化を阻む安定性と価格に関する懸念を払拭する高効率な基礎的水電解槽の創出を目指す。
