Electrochemcial Energy Systems Laboratory


Electrochemical Energy Conversion and Storage: Fuel Cells, Flow Batteries, Electrochemical Flow Capacitors, Transport Phenomena, Microstructure Characterization, System Design and Diagnostics

Research Interests

We are working on next generation energy storage and conversion systems for use in transportation, portable and grid-scale applications. Our studies consist of experimental and computational studies aimed at understanding the mass/charge transport phenomena, the internal structure of materials, performance diagnostics, and system design to address the scientific challenges in these emerging systems.


E. Caglan Kumbur is an Assistant Professor in the Mechanical Engineering and Mechanics Department and the principal investigator of the Electrochemical Energy Systems Laboratory.  He received a B.S. in Mechanical Engineering from Middle East Technical University in Turkey, and M.S. and Ph.D. Degrees in Mechanical Engineering from Pennsylvania State University.

He currently serves as Associate Editor for the International Journal of Hydrogen Energy.
