Professor Miyatake's research focuses on polymer materials for electrochemical energy devices, with particular emphasis on proton exchange membranes (PEMs) and anion exchange membranes (AEMs) for fuel cells and water electrolyzers. His work spans fundamental polymer chemistry, membrane structure-property relationships, and practical device applications. He has pioneered the development of polyphenylene-based membranes that offer superior performance and durability compared to conventional materials. His recent research has expanded into solid-state rechargeable air batteries and advanced water electrolysis systems.

Analysis of his 15 most recent publications (2024-2025) reveals a strong focus on membrane design for water electrolysis applications, with significant work on anion exchange membranes containing piperidinium and fluorene structures. His research consistently addresses critical challenges in membrane technology including chemical stability in alkaline environments, hydroxide ion conductivity, mechanical reinforcement, and dimensional stability. The publications demonstrate a sophisticated approach to polymer engineering with precise control over hydrophobic/hydrophilic domain structures.

• BCSJ Award Article (2022.05) for work on sulfonated aromatic terpolymers
• Minister of Education Commendation (2021.04) for research on innovative polymer thin films for fuel cells
• 25th Yamanashi Academy of Sciences Award (2020.11) for development of high-performance ion-conducting polymers
• German Innovation Award Gottfried Wagener Prize (2013.06)
• Multiple awards from professional societies including Chemical Society of Japan and Society of Polymer Science

Professor Miyatake actively advises research projects and has established significant collaborations both within Japan and internationally. His work has been supported by major funding agencies including the Japan Society for the Promotion of Science. He maintains leadership roles in professional organizations including the Hydrogen Science and Technology Collaboration Research Association where he serves as Director. His laboratory employs advanced characterization techniques including neutron reflectometry, small-angle X-ray scattering, and current-sensing atomic force microscopy to investigate membrane structure-property relationships.
