Energy Device Visualization Technology Lab
Machine-translated · View original
A lab that researches visualization technology to make the inside of fuel cells visible.
AboutAbout the lab
Capturing the inside of fuel cells through visualization
Associate Professor Yuya Tachikawa, at the Hydrogen Utilization Process Lab, develops technology that visualizes the phenomena occurring inside fuel cells.
The lab aims to realize an environmentally friendly hydrogen energy society centered on fuel cells.
Temperature changes, chemical reactions, and thermal stress distributions that cannot normally be observed are evaluated using numerical analysis and experimental visualization methods.
The lab also develops system analysis methods for evaluating fuel cell systems at the macro level.
Key terms
- Solid oxide fuel cell (SOFC)
- A fuel cell that uses a solid oxide as its electrolyte. It is being researched as a next-generation type that can use a wide variety of fuels
- Reversible cell
- A cell that can both generate power as a fuel cell and perform steam electrolysis
- Thermal stress
- Stress that arises inside an object when its temperature changes or differs from place to place
- Numerical analysis
- A method of studying a phenomenon by calculating it numerically on a computer
ResearchResearch themes
The 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. Within this work, Associate Professor Tachikawa is engaged in developing visualization methods that make the phenomena occurring inside fuel cells visible, among other topics.
*Illustrative imageElectrode materials and processes for SOFCs
The lab develops solid oxide fuel cells (SOFCs) with high performance and excellent durability, while clarifying the reaction processes and thermodynamic stability of the cells. In an international collaboration with MIT, it also aims to develop reversible cells capable of both power generation and steam electrolysis.
