| Outline of Final Research Achievements |
We have studied miniature fuel cells with monolithically fabricated Si electrodes. In this study, we aimed to solve several problems and enable use of biomass derived hydrogen in our fuel cells. Then, we proposed “polymer electrolyte membrane with adapted shape to the electrode” and “high CO tolerant multi layered catalyst layer”.
In this study, the adapted shape membrane was realized by employing plasma etching in a preparation step of a porous polymer base membrane. Power generation was demonstrated with the novel membrane and significant improvement was obtained. High CO tolerant catalyst was also realized by electrochemical atomic layer deposition on a porous Au, and promising results were observed.

| Academic Significance and Societal Importance of the Research Achievements |
提案した「電極板に密着する異形電解質膜」と「多層構造による高CO 耐性触媒層」をともに実現することができた。共に独創的な成果と考えている。異形電解質膜は、他グループのMEMS型燃料電池研究においても活用可能と考えられる。また、今回実現したAu-Pd-Pt多層触媒は、大きな燃料電池を含めて、PdおよびPtの使用量を抑えつつ高CO耐性を持った触媒として、有望な成果と考えている。
