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.

Solar-induced hybrid fuel cell produces electricity directly from biomass

February 19, 2014 7:45 am | by John Toon, Georgia Institute of Technology | News | Comments

Although low-temperature fuel cells powered by methanol or hydrogen have been well studied, existing low-temperature fuel cell technologies can’t directly use biomass as a fuel because of the lack of an effective catalyst system for polymeric materials. Now, researchers have developed a new type of low-temperature fuel cell that directly converts biomass to electricity with assistance from a catalyst activated by solar or thermal energy.

Nanocrystal catalyst transforms impure hydrogen into electricity

September 18, 2013 2:20 pm | News | Comments

Carbon monoxide is a poisoning impurity in hydrogen derived from natural gas. If a catalyst could be developed that can handle this impure fuel, it could be a substantially less expensive alternative to pure hydrogen produced from water. Scientists at Brookhaven National Laboratory have used a simple, “green” process to create a new core-shell catalyst that tolerates carbon monoxide in fuel cells.
