Major Research Topics in Laboratory

Global environmental issues as well as resource depletion problems, which are strongly related to the sustainability of our mother earth, are big issues for us to tackle in this century. We will challenge a variety of topics related to future energy technologies for sustainability.

1. Theoretical Study on Solid Oxide FUel Cell (SOFC)

SOFC is an ultimate energy conversion technology, which is expected to have such high efficiency of 60% by the combined system with turbines. For the market penetration of SOFC, we are conducting theoretical study on physics in complex porous electrode system for designing porous structure. Simultaneously, we aim at establishing porous system engineering by abstracting essential knowledge from the very specific phenomena in the system.

2. Theoretical Study on Lithium Ion Battery

We are conducting a multi-scale computational chemistry study on a mechanism of lithium ion flow within a porous electrode system collaborating with researchers in industry.

3. Novel Nano-alloy systems for H2 absorption and catalysis

To clarify the catalytic and hydrogen absorption propertirs of nano-alloys synthesized by Prof. Kitagawa of Kyoto University, we are conducting a fundamental theoretical study on the emergence of those properties in nano-alloy systems.

4. Challenge for developing practical multi-scale/multi-physics simulation systems

To clarify the complex multi-physics in porous material systems such as fuel cell electrodes, we are developing original simulation programs.

5. Grand design of future sustainable energy society

We are developing a vision and pathways toward the sustainable energy utilization in future Japanese society collaborating with researchers in different institutes.

    No need for nobles: The copper-based metal–organic framework material N,N'-bis(2-hydroxyethyl)dithiooxamidatocopper(II) (see picture, Cu pink, N blue, S yellow, O red, C gray, H white) is an active catalyst for ethanol electrooxidation. The performance of this noble-metal-free material is comparable to those of some reported Pt-based catalysts.
