Enzymes Get A Protective Shield
September 19, 2018 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Ruhr-University Bochum researchers have developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. These enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable when they come into contact with oxygen. They are therefore not yet suitable for technological applications. The new protective mechanism is […]

Penn State researchers believe they have developed a 10-fold increase in the ability to harvest mechanical and thermal energy over standard piezoelectric composites. The new system may be possible using a piezoelectric ceramic foam supported by a flexible polymer support. In the search for ways to harvest small amounts of energy to run mobile electronic […]

Georgia Institute of Technology researchers’ nanoparticle coating processing of oxygen on the cathode end of solid oxide fuel cells increases by eightfold the current best performance. Zero-emissions cars zipping into a sustainable energy future are just one dream powered by fuel cells. But fuel cell technology has been a little sluggish and fuel prohibitively pricey. […]

A Self Oxygen Protected Fuel Cell
March 22, 2018 | Leave a Comment
Small traces of oxygen can deactivate the molecular catalysts that are incorporated in fuel cells. A team of researchers from the Ruhr-Universität Bochum (RUB), the Max-Planck-Institute for Energy Conversion in Mülheim and the Pacific Northwest National Laboratories in Washington, U.S.A., is able to equip such a catalyst with a self-defense mechanism against molecular oxygen. Hydrogen […]
