Equipped
with a fuel cell by Clarkson University engineers, a snail was able to
regenerate glucose consumed by biocatalytic electrodes, and, upon
feeding and relaxing, produce a new portion electrical energy. The
world's first "electrified snail" joins menagerie of cockroaches, rats,
rabbits, and other animals previously implanted with biofuel cells that
generate electricity.

It took Thomas Edison two years and over 3,000 experiments to develop a marketable light bulb. It has taken 10 times that long and who-knows-how-many experiments to develop a system that is far more complicated: The inner workings of a reliable, marketable hydrogen fuel cell. Now a Michigan Technological University research team is nearing development of a mathematical model that will slash that R&D time and effort.

For catalysts in fuel cells and electrodes in batteries, engineers would like to manufacture metal films that are porous, to make more surface area available for chemical reactions, and highly conductive, to carry off the electricity. The latter has been a frustrating challenge. But Cornell University chemists have now developed a way to make porous metal films with up to 1,000 times the electrical conductivity offered by previous methods.

In
a new world record for stationary applications, a planar solid oxide
fuel cell built at Jülich Institute of Energy and Climate Research in
Germany has exceeded an operating lifetime of 40,000 hours. Powered by
hydrogen, the cell functioned for the equivalent of five years at 64%
electricity conversion efficiency.

The University of Connecticut's Center for Clean Energy Engineering has developed a new manufacturing process for fuel cells that could make highly efficient, fuel cell-powered vehicles a viable commercial option in the next 10 years and possibly sooner.

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.

Chemists at Brown University have created a triple-headed metallic nanoparticle that reportedly performs better and lasts longer than any other nanoparticle catalyst studied in fuel-cell reactions. The key is the addition of gold: It yields a more uniform crystal structure while removing carbon monoxide from the reaction.

Production of energy from the difference between salt water and fresh water is most convenient near the oceans, but now, using an ammonium bicarbonate salt solution, Penn State University researchers can combine bacterial degradation of waste water with energy extracted from the salt-water fresh-water gradient to produce power anywhere.
