| Outline of Final Research Achievements |
Hydrogen has attracted much attention for the efficient use of renewable energy without emission of CO2. Water electrolysis converting electricity to hydrogen and polymer electrolyte fuel cell converting hydrogen to electricity have problems about durability of electrodes which degrade by corrosion, dissolution, and/or delamination due to frequent power fluctuation and/or start/stop operation. In this research, novel materials, such as porous conductive metal oxides and hybrid nanosheets were developed as highly durable electrode materials. These new technologies will contribute to cost reduction of hydrogen energy in our society.

| Academic Significance and Societal Importance of the Research Achievements |
地球温暖化の進行を食い止めるためには、CO2を排出しないクリーンな再生可能エネルギーの利用が必須である。再生可能エネルギー（太陽光、風力、水力、地熱など）は発電時間や発電場所が限られており、水素等の貯蔵、輸送に敵した形で取り扱う必要がある。本研究の成果は、水素利用、水素製造の装置の高寿命化に貢献する技術であり、将来社会において水素エネルギーを利用する際のコスト低減に寄与すると期待される。
