[WATCH]: What's in a Fuel Cell?

Daniel Sieberg interviews Dr. Cynthia Lundgren, chief of the Electrochemistry Branch in the Sensors and Electron Devices Directorate at the Army Research Laboratory in Adelphi, Md. Lundgren takes us on a tour of her lab, describing an experiment where a scientist is working to extract sulfur from a chemical compound at room temperature, using synthetic compounds, something she says is very hard to do. In another experiment, a researcher is working to purify gas streams to go into a fuel cell, working to develop materials that will extract hydrogen to power fuel cells. She demonstrates equipment that measures the speed of a reaction using electrodes. It's used to determine which is the best chemical or compound to use to extract diffe
