Sasabe Lab
Machine-translated · View original
A lab that tackles energy and environmental problems with state-of-the-art measurement and analysis.
AboutAbout the lab
Addressing energy and environmental problems with state-of-the-art measurement and analysis.
The Sasabe Lab studies how to use clean energy with high efficiency and reduce carbon dioxide emissions.
It investigates what happens inside electrochemical devices such as fuel cells and lithium-ion secondary batteries.
Using X-ray visualization measurement and numerical thermofluid analysis, the lab tracks transport phenomena occurring at the nano- and micro-scale.
Its themes span many areas, from next-generation lithium-ion batteries to geological sequestration of carbon dioxide.
Key terms
- Fuel cell
- A device that extracts electricity by reacting hydrogen and oxygen. Generating power produces only water.
- Electrochemical devices
- A group of devices, such as batteries, that operate through chemical reactions and the exchange of electricity.
- Visualization measurement
- Measuring by turning the internal state of something that cannot be seen from outside into images.
ResearchResearch themes
The lab pursues research from many angles that contributes to using clean energy efficiently and reducing carbon dioxide emissions. Using X-ray visualization measurement and numerical thermofluid analysis, it investigates nano- and micro-scale transport phenomena occurring inside electrochemical devices such as fuel cells and lithium-ion secondary batteries.
*Illustrative imageUltra-thin gas diffusion layers for fuel cells
Making the layer that serves as the pathway for gas and water thinner is effective for improving fuel cell performance. The lab makes extremely thin layers from nanofibers and tests how much performance improves at channel widths close to those of actual cells.
*Illustrative imageHow catalyst layers are coated, and the water inside
A fuel cell catalyst layer is made by coating catalyst ink and drying it. The lab examines how coating stability, drying temperature, and ink mixing affect performance, and also uses X-ray CT to observe water that accumulates in the layer during power generation.
