A Basic Overview Of Fuel Cell Technology

By John on January 24, 2010

Are you tired of high priced gasoline for your car? Or perhaps worried about the environment? For years, scientists have being working on an energy alternative that holds promises to change the way we live by changing the source of fuel for some of our most basic energy-using engines. This new technology in progress is [...]

Improving Performance of Nanotubes in Solar Cells that Produce Hydrogen Gas from Water

By John on May 8, 2009

A research team from Northeastern University and the National Institute of Standards and Technology (NIST) has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes-a residue that wasn’t even noticed before this-plays an important role in improving the performance of the nanotubes in solar cells that produce hydrogen gas [...]

What is a Fuel Cell?

By John on September 7, 2008

Fuel cells are electrochemical devices that convert a fuel’s chemical reaction in an electrolyte directly into electrical energy from fuel (on the anode side) and an oxidant (on the cathode side).
While they are similar to batteries in that they have no moving parts, batteries store their energy whereas fuel cells can produce electricity continuously as [...]
