A hydrogen energy lab that makes the inside of fuel cells visible.
AboutAbout the lab
Making the inside of fuel cells visible.
Associate Professor Yuya Tachikawa is developing high-temperature fuel cells and methods to analyze them, with the theme of achieving high-efficiency power generation aimed at reducing CO2.
In the Hydrogen Utilization Process Lab, Associate Professor Tachikawa and colleagues are researching how to visualize, through numerical analysis and experiments, the temperature changes, chemical reactions, and thermal stress distribution that occur inside fuel cells.
Based on a vision of a future hydrogen-based society, the lab also examines the effects of producing hydrogen with renewable energy and develops technologies toward CO2-free energy.
This lab site belongs to the Hydrogen Utilization Process Lab headed by Professor Kazunari Sasaki, and Associate Professor Tachikawa is listed as a member.
Key terms
- SOFC
- Short for solid oxide fuel cell. A type of high-temperature fuel cell, being researched as a next-generation fuel cell that can flexibly use diverse fuels.
- Thermal stress
- Force generated inside a material, for example when temperature differs from place to place.
- System analysis
- A method for evaluating an entire fuel cell system at the macro level.
ResearchResearch themes
As a member of the Hydrogen Utilization Process Lab, Associate Professor Tachikawa works on developing technologies to visualize the phenomena, reactions, and structural changes inside fuel cells, which are needed to develop next-generation high-performance fuel cells. Alongside this, the work includes developing high-temperature fuel cells and studies toward a hydrogen-based society.

Aiming for the practical use of next-generation fuel cells that can flexibly use diverse fuels, the lab develops high-performance, highly durable cells while clarifying the reaction processes and thermodynamic stability in the cells.
*Illustrative imageVisualizing the Inside of Fuel Cells
The lab evaluates temperature changes, chemical reactions, and thermal stress distributions, which cannot normally be observed, using visualization methods based on numerical analysis and experiments. It also develops system analysis methods for evaluating fuel cell systems at a macro level.
*Illustrative imageHydrogen Production and CO2-Free Energy
Based on a vision of a future hydrogen-based society, the lab examines the effects of producing hydrogen with renewable energy. It is also advancing development toward CO2-free energy.
