Héctor Daniel Abruña (born 1953) is a Puerto Rican physical chemist whose work focuses on electrochemistry, molecular electronics, fuel cells, batteries, and electrocatalysis.
[3] Abruña conducts research into battery and fuel cell systems using electrochemical techniques and X-ray microscopy and spectroscopy methods.
[23][24][25][26] He also co-founded the startup company Ecolectro with Geoffrey W. Coates,[27][28] which received funding from both the Department of Energy and the National Science Foundation.
[6] In 2016, Abruña developed a device that combines the large energy-storage capacity of batteries with the high charge-discharge rate of supercapacitors.
[33][34] Abruña created extremely small light sources with sizes of only hundreds of nanometers by depositing light-emitting polymer fibers on a silicon substrate patterned with gold electrodes.
