Title: Mechanical and Material Aspects in PEM Fuel Cell R&D
Abstract: Polymer electrolyte membrane (PEM) fuel cells are
electrochemical devices that can directly convert the chemical
energy stored in hydrogen into electrical energy with a peak
conversion efficiency as high as 65%. Mechanical and material
properties play a crucial role in fuel cell performance. New
catalyst materials are urgently needed to improve fuel cell
durability under low loading. Advanced manufacturing methods can
help to reduce fuel cell cost and precious material use. In this
talk, I will present several important research & development
(R&D) efforts in the mechanical and material aspects for fuel
cells, including measurement of membrane properties and water,
electrode design for cold start, ultralow Pt loading catalyst
layer fabrication, and novel porous-media flow fields.
Prof. Takahiro Namazu
Kyoto University of Advanced Science, Japan
Takahiro Namazu received the B.S., M.S., and Ph.D. degrees in mechanical engineering fromRitsumeikan University, Kusatsu, Japan, in 1997, 1999, and 2002, respectively.From 2002 to 2006, he was an Assistant Professor with the Department ofMechanical and Systems Engineering, Graduate School of Engineering, theUniversity of Hyogo, Himeji, Japan. In 2007, he became an Associate Professorat the university. In 2010, he joined the Precursory Research for EmbryonicScience and Technology (PRESTO) program, “Nanosystems and Emergent Functions”of the Japan Science and Technology Agency (JST), as a Researcher. In the JSTPRESTO program, his research project was the emergence of self-propagatingexothermic nanomaterials for future semiconductor industry and human life care.In 2016, he became a Professor of the Department of Mechanical Engineering,Aichi Institute of Technology, Toyota, Japan. In 2019, he joined the KyotoUniversity of Advanced Science (KUAS), Kyoto, Japan, as a Visiting Professor.In 2020, he will become a Professor with the Faculty of Engineering, KUAS. Heis currently engaged in studies on functional film materials, such asself-propagating exothermic materials, and their applications to micro/nanoelectro-mechanical systems (NMEMS). His research interests also include thedevelopment of material testing techniques for measuring the mechanicalproperties of micro/nanoscale materials, such as carbon nanotubes and siliconnanowires, which focuses on clarifying the nanomaterials’ size effect phenomenaand these mechanisms. The evaluation of the reliability of MEMS andsemiconductor devices is included as well in his interests for realizing thedesign of ultra-long life microdevices.Dr. Namazu has earned over 20 research awards for hisoutstanding materials research results and his contributions to the evolutionof the micro/nanoscale materials science field in the world.
