Our work is focused on electrochemical energy engineering (see the first publication below with downloadable PDF of a Perspective). Of particular recent interest is the design, fabrication, and performance testing and modeling of polymer hydroxide exchange membrane based electrochemical energy conversion and storage devices including fuel cells, electrolyzers, and flow batteries. To be commercially viable, these electrochemical devices need to meet certain performance, cost, and durability targets, and for that purpose, novel catalysts and polymer electrolytes are designed, synthesized, and implemented in devices. We also study fundamental electrocatalysis by using classic electrochemistry techniques and simulations, and probe the electrochemical interfaces with surface enhanced spectroscopies. We collaborate extensively with our colleagues within UD as well as outside it.
