Miniaturized Fuel Cells Maximize the Flight Time of Drones for Humanitarian Missions
January 19, 2021 by Jake Hertz
One of the prevailing challenges of drone electronics is extending battery life. In a new announcement, researchers in Korea say they ve found the key: miniaturized fuel cells.
For portable electronics, one of the most significant design challenges for engineers is how to increase battery life. Generally, there are two approaches: either make low-power electronics or create batteries that can go long stretches in between charges.
Drones are no exception to this design challenge. The average drone today gets about one hour of flight before it needs to be recharged. This could severely hinder a drone’s usefulness, especially when it is used for things like disaster relief.

The COVID-19 pandemic has been increasing the fears of new pathogens like drug-resistant bacteria or new viruses. A Korean research group has recently gained attention for designing a new technology to eliminate antibiotic-resistant bacteria by regulating the surface texture of nanomaterials.

A collaborative research group from Pohang University of Science and Technology (POSTECH) and UNIST has described a mixed-FeCo-oxide-based surface-textured nanostructures (MTex) as a highly effective magneto-catalytic platform in
Nano Letters, an international journal.
The team included professors In Su Lee and Amit Kumar together with Dr Nitee Kumari from POSTECH’s Department of Chemistry and Professor Yoon-Kyung Cho and Dr Sumit Kumar from UNIST’s Department of Biomedical Engineering.
