Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Hydride-ion conduction makes its first appearance
Ionic transport has been studied extensively over the years for energy devices such as fuel cells and batteries using Li+, H+, Ag+, Cu+, F-, and O2-. Yet as researchers point out in a recent report, hydride ions (H-) may be particularly useful for high-energy-density storage and conversion devices. Using an oxyhydride solid state cell they have now demonstrated pure H- conduction in an oxide for the first time.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Engineers adapt laser method to create micro energy units
As the demand for thinner microelectronic devices increases, manufacturers often are limited by how oddly shaped the energy sources must become to make them conform to the smaller space. Now, researchers have developed a method of transferring an energy source to virtually any shape. Using direct laser-writing techniques, scientists can help smartphone manufacturers fabricate energy storage units such as micro fuel cells that are environmentally friendly, highly designable and thin.
