Engineering a more efficient fuel cell

July 9, 2014 10:38 am | by Glen Martin, Stanford New Service | News | Comments

Using high-brilliance x-rays, Stanford Univ. researchers track the process that fuel cells use to produce electricity, knowledge that will help make large-scale alternative energy power systems more practical and reliable. Fuel cells use oxygen and hydrogen as fuel to create electricity; if the process were run in reverse, the fuel cells could be used to store electricity, as well.

Designing ion “highway systems” for batteries

June 10, 2014 2:19 pm | News | Comments

Since the early 1970s, lithium has been the most popular element for batteries because of it’s low weight and good electrochemical potential. But it is also highly flammable. Researchers have recently married two traditional theories in materials science that can explain how the charge dictates the structure of the material. And using this they may be able to move to other materials, such as block copolymers, for use in batteries.
