Welcome to Tominaga Laboratory

Tominaga Laboratory is a laboratory of “electrochemistry”.
Electrochemistry deals with the interconversion of chemical and electrical energies. The fields range from biological energy production to fuel cells.
In our laboratory, we specifically carry out research in the field of bioelectrochemistry. We are focusing in research and development of enzyme-catalyzed fuel cells and microbial fuel cells. We are also actively engaged in joint research with companies.

News

We have started laboratory activities for the new year.　NEW
