New Polymer Fuel Cell Runs With Higher Power Density
February 8, 2022 | Leave a Comment
Los Alamos National Laboratory’s new fuel cell with a higher-rated power density than state-of-the-art fuel cells can operate at 80-160° Celsius. The new cell solves the longstanding problem of overheating, one of the most significant technical barriers to using medium-and heavy-duty fuel cells in transportation vehicles such as trucks and buses. Because current fuel cells […]

The View Of Piezoelectric Materials Is Getting An Update
December 14, 2021 | Leave a Comment
For years, researchers believed that the smaller the domain size in a ferroelectric crystal, the greater the piezoelectric properties of the material. However, recent findings by Penn State researchers have raised questions about this standard rule. Piezoelectricity is a material property where a crystal generates electrical charge under an applied mechanical force. This capability enables […]

An Ocean Wave Generator That Works like Seaweed
November 30, 2021 | Leave a Comment
Researchers at Dalian Maritime University, Marine Engineering College reported they have developed flexible power generators that mimic the way seaweed sways to efficiently convert surface and underwater waves into electricity to power marine-based devices. Ocean waves can be powerful, containing enough energy to push around sand, pebbles and even boulders during storms. These waves, as […]
