AboutAbout the lab
Creating functional materials that contribute to a green hydrogen society
Matsuzawa Lab (Materials Electrochemistry Laboratory) studies materials for the electrochemical devices needed for a green hydrogen society.
For fuel cells, which use hydrogen, and water electrolysis, which produces hydrogen, the lab works on improving the performance and durability of electrode materials and on clarifying the mechanisms of electrode reactions.
On the academic side, the lab focuses on electrochemical phenomena at interfaces and studies technologies for storing and using energy through the interconversion of electrical and chemical energy.
Key terms
- Green hydrogen
- Hydrogen produced with electricity from renewable energy, without emitting CO2 even during the production process
- Water electrolysis
- A technology that produces hydrogen by splitting water with electricity; the main types are alkaline water electrolysis and polymer electrolyte water electrolysis
- Non-precious-metal oxide
- An oxide-based material that does not use precious metals such as platinum; the lab focuses on its abundance, low cost, and high stability

ResearchResearch themes
The lab studies electrode materials for the electrochemical devices needed for a green hydrogen society, aiming for higher performance and durability. For fuel cells and water electrolysis, it develops non-precious-metal oxide catalysts and advances fundamental understanding of electrode reactions.
*Illustrative imageNon-precious-metal catalysts for fuel cells
Polymer electrolyte fuel cells use platinum as a catalyst, which is expensive and limited in supply. The lab aims to use non-precious-metal oxide materials, which are abundant, inexpensive, and highly stable, as catalysts for the cathode (air electrode), where energy loss is large. This is joint research with Prof. Ishihara (Project Professor).
*Illustrative imageOxide catalysts for alkaline water electrolysis
Alkaline water electrolysis has long been an industrial method of producing hydrogen and is expected to be the leading option for large-scale green hydrogen production. Because nickel electrocatalysts degrade when operated with fluctuating electric power, the lab studies using oxide materials, which are abundant and highly stable, as anode catalysts.
*Illustrative imageOxide catalysts for polymer electrolyte water electrolysis
Polymer electrolyte water electrolysis allows compact equipment and yields high-purity hydrogen, and it is expected to serve as a decentralized option. The lab aims to replace the scarce iridium used in the anode with non-precious-metal oxide materials that are abundant, inexpensive, and highly stable.
