ORNL microscopy reveals workings behind promising inexpensive catalyst

Gabriel — Tue, 12 Jun 2012 19:44:57 +0000

A newly developed carbon nanotube material could help lower the cost of fuel cells, catalytic converters and similar energy-related technologies by delivering a substitute for expensive platinum catalysts. The precious metal platinum has long been prized for its ability to spur key chemical reactions in a process called catalysis, but at more than $1,000 an […]

Unzipped carbon nanotubes could help energize fuel cells and batteries

Gabriel — Tue, 29 May 2012 17:28:22 +0000

Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at Stanford University. Their findings are published in the May 27 online edition of the journal Nature Nanotechnology. “Platinum is very expensive and thus impractical for […]

More efficient and cost effective hydrogen fuel cells

Gabriel — Thu, 15 Mar 2012 20:02:46 +0000

Hydrogen fuel cells, like those found in some “green” vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective. A research team from the University of Central Florida may have found a way around both hurdles. The […]

The hydrogen powered cleaning vehicle in operation on the streets of Basel – Germany

Gabriel — Tue, 13 Mar 2012 19:53:02 +0000

Since 2009, a hydrogen powered street cleaning vehicle has been undergoing testing on the streets of Basel. The project is intended to take hydrogen drives out of the laboratory and onto the streets in order to gain experience on using them under practical conditions. The result of the pilot trial: hydrogen as a fuel for […]

Bugs from space to increase the electrical output of the fuel cells

Gabriel — Wed, 22 Feb 2012 19:29:51 +0000

Bacteria normally found 30km above the earth have been identified as highly efficient generators of electricity. Bacillus stratosphericus – a microbe commonly found in high concentrations in the stratosphere orbiting the earth with the satellites – is a key component of a new ‘super’ biofilm that has been engineered by a team of scientists from Newcastle […]

Novel Materials for Hydrogen Storage

Gabriel — Thu, 26 Jan 2012 19:01:16 +0000

The biggest challenge with hydrogen-powered fuel cells lies in the storage of hydrogen: how to store enough of it, in a safe and cost-effective manner, to power a vehicle for 300 miles? Lawrence Berkeley National Laboratory (Berkeley Lab) is aiming to solve this problem by synthesizing novel materials with high hydrogen adsorption capacities. The U.S. […]

How Fuel Cells working on the nanoscale

Gabriel — Fri, 30 Dec 2011 20:18:53 +0000

For the first time, physical chemistry reactions in a fuel cell can now be observed and described in detail on the nanoscale. This innovation is due to a new microscopy technique devised by an international research team involving Heidelberg mathematician Dr. Francesco Ciucci and scientists from the United States and Ukraine. The new technique means […]
