Shikazono Lab
Machine-translated · View original
A lab that uses energy without waste, through fuel cells and heat pumps.

AboutAbout the lab
Technology that uses energy without waste.
The Shikazono Lab studies solid oxide fuel cells (SOFCs) and next-generation heat pumps and steam engines.
Both are expected to be technologies that use energy effectively, with small exergy losses.
Using both experiments and numerical simulation, the lab works to improve performance and reliability, from the fine structure of electrodes to entire devices.
Students are assigned to the lab from the Department of Mechanical Engineering, Graduate School of Engineering.
Key terms
- SOFC
- Solid oxide fuel cell. A fuel cell that uses a solid oxide as its electrolyte and operates at high temperatures.
- Exergy
- The portion of energy that can be extracted as work, such as mechanical power or electricity.
- Two-phase flow
- Flow in which substances in different states, such as a liquid and a gas, flow together.

ResearchResearch themes
The lab's research centers on solid oxide fuel cells (SOFCs) and next-generation heat pumps and steam engines. By developing experimental and numerical methods, it aims to create highly efficient and reliable devices that use energy effectively.
*Illustrative imageExperiments and numerical analysis of fuel cells (SOFCs)
To improve the reliability and efficiency of SOFCs, the lab directly measures the three-dimensional fine structure of electrodes with electron microscopy and simulates the diffusion and electrochemical reactions within it.
*Illustrative imageLiquid and vapor flowing in narrow channels
To make the heat exchangers of heat pumps and steam engines smaller and lighter, the lab investigates, through measurement and modeling, the phenomenon in which a thin liquid film and vapor flow together inside extremely narrow channels (two-phase flow).
*Illustrative imageKey technologies for next-generation heat engines
To make heat pumps and steam engines that operate on small temperature differences higher in performance, more reliable, smaller, and cheaper, the lab proposes and demonstrates new mechanisms based on fundamental research.
