Electrode Materials and Porous Diffusion Layers Lab (Masahiro Yasutake)
Machine-translated · View original
The lab designs the electrodes and cell structures of fuel cells and water electrolyzers.
AboutAbout the lab
Designing electrodes and structures for fuel cells and water electrolysis.
The Electrode Materials and Porous Diffusion Layers Lab studies fuel cell and water electrolysis technologies, which handle energy conversion for renewable energy and hydrogen.
In water electrolysis, which splits water with electricity to produce hydrogen, the lab works on designing cell structures that achieve both high efficiency and high durability while reducing the amount of precious metals used.
For solid oxide cells, which operate at high temperatures, the lab investigates the relationship between electrode degradation and the acid-base properties of the electrode surface through international collaborative research.
The lab's website presents it within the research of the Hydrogen Utilization Process Lab.
Key terms
- Precious metals
- Metals such as platinum and iridium. In water electrolysis cells, reducing the amount used is considered a key challenge.
- Solid oxide type
- One type of fuel cell or water electrolysis cell that operates at high temperatures. It does not require precious metals.
- Reversible cell
- A cell that can be used both for power generation as a fuel cell and for steam electrolysis.
ResearchResearch themes
The Hydrogen Utilization Process Lab's website presents research on materials and processes toward realizing a hydrogen energy society centered on fuel cells. Within it, Assistant Professor Masahiro Yasutake works on the structure of water electrolysis cells and on electrodes.
*Illustrative imageNext-Generation Electrodes for Polymer Electrolyte Fuel Cells
The Hydrogen Utilization Process Lab develops new fuel cell electrode catalysts that offer high performance and high durability, and is building guidelines for material design starting from the catalyst support. Its results include electrode catalysts that use an oxide as the support, which fundamentally solves the problem of carbon corrosion.
*Illustrative imageElectrodes and Reactions in Solid Oxide Fuel Cells
Aiming for practical use of next-generation fuel cells that can flexibly use a variety of fuels, the Hydrogen Utilization Process Lab studies cell reactions and thermodynamic stability. In international collaborative research with MIT, it aims to develop reversible cells capable of both power generation and steam electrolysis.
*Illustrative imageNew Cell Structures for Polymer Electrolyte Water Electrolysis
The lab is developing new cell structures aimed at higher performance, higher durability, and lower precious metal content in water electrolysis cells. It conducts demonstration research on a new concept that expands the functions of a component called the diffusion layer so that the precious metals in the cell are used effectively, achieving both reduced usage and higher performance, and it also evaluates the effect on durability.
