Electrode Materials and Porous Transport Layers Lab
Machine-translated · View original
A lab that studies the structural design of water electrolysis cells and electrode degradation in solid oxide cells.
AboutAbout the lab
Structural design of water electrolysis cells and evaluation of electrode degradation
The research of Assistant Professor Masahiro Yasutake focuses on fuel cell and water electrolysis technologies, which handle energy conversion between renewable energy and hydrogen.
For polymer electrolyte water electrolysis cells, the lab works on structural design that achieves high efficiency and high durability at the same time while reducing the use of precious metals.
For solid oxide cells, which operate at high temperatures, the lab evaluates the relationship between electrode degradation and the acidity and basicity of the electrode surface in an international collaboration.
The lab's website is that of the Hydrogen Utilization Process Lab, led by Chief Professor Kazunari Sasaki.
Key terms
- Water electrolysis
- A technology that produces hydrogen by splitting water with electricity. The polymer electrolyte type is attracting attention for production from fluctuating renewable energy
- Porous transport layer
- A component of a water electrolysis cell. Research is being conducted on expanding its functions to make effective use of the precious metals in the cell
- Solid oxide type
- A type of cell that operates at high temperatures. It does not require precious metal materials and can perform highly efficient power generation and steam electrolysis
ResearchResearch themes
The Hydrogen Utilization Process Lab aims to realize a hydrogen energy society centered on fuel cells, and studies the materials and processes of fuel cells and related hydrogen systems. This page introduces the themes involving Assistant Professor Yasutake: solid oxide fuel cells and polymer electrolyte water electrolysis cells.
*Illustrative imageElectrodes for solid oxide fuel cells
The lab develops fuel cells with high performance and excellent durability, while clarifying the reactions and thermodynamic stability of the cells. In an international collaboration with MIT, it aims to develop reversible cells capable of both power generation and steam electrolysis.
*Illustrative imageDesign of polymer electrolyte water electrolysis cells
The lab develops new water electrolysis cell structures aiming at high performance, high durability, and reduced use of precious metals. It conducts demonstration studies that expand the functions of the porous transport layer to make effective use of the precious metals in the cell, and that evaluate the effect on durability.
