Scientists at Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruhe Institute of Technology in Germany have developed a new energy conversion and storage system using seawater for the cathode in a fuel cell. We’ve seen that sodium can serve as an alternative to lithium in rechargeable batteries. That’s because the reversible […]

UmeĆ„ University reports Swedish and Chinese researchers are showing how a unique nano-alloy composed of palladium nano-islands embedded in tungsten nanoparticles creates a new type of catalyst for fuel cells. The new type of catalyst is highly efficient at oxygen reduction, the most important reaction in hydrogen fuel cells. The team’s paper has been published […]

Rice University scientists combined graphene quantum dots drawn from common anthracite coal with graphene oxide, nitrogen and boron into a catalyst for fuel cells that outperforms the expensive rare earth platinum. In a fuel cell application the graphene quantum dots grab onto graphene platelets like barnacles attach themselves to the hull of a boat. The […]

Scientists at the Center for Research in Advanced Materials (CIMAV) have developed a device that fits inside a pair of shoes that harvests the energy made available when someone walks. This energy is then stored in AAA or watch batteries. The team designed a pill-shaped cylinder adapted to a shoe in order to store the […]

A study by a team from the Institute of Vehicle Concepts, German Aerospace Center (DLR) on the total cost of ownership (TCO) strongly suggests car manufacturers should develop a modular battery design for plug-in hybrid and extended range electric vehicles (PHEVs and EREVs). That simple change would allow consumers a choice of storage capacity to […]
