Fuel cells are simple devices, containing no moving parts and only four functional component elements: cathode, electrolyte, anode and interconnect. Fuel cells are actually being used more widely than many people think.
Fuel cells are electrochemical devices similar to batteries that directly convert chemical energy of a fuel into electrical energy and heat. They are different [...]

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 [...]

Empa and the Paul Scherrer Institute (PSI) have, together with Bucher Schoerling, Proton Motor, BRUSA Elektronik AG und Messer Schweiz, developed a hydrogen powered municipal street cleaning vehicle which was presented to the public on 14th May 2009 in Basel. The vehicle is named the “Bucher CityCat H2″ and is the first municipal utility vehicle [...]

One of the main aims in the field of hydrogen car research is the development of a good fueling system, ie. a system that would allow travelers to fill their vehicles’ fuel cells in less than 5 minutes, and then drive some 300 miles with a single charge. Making this happen is not as easy [...]

Hydrogen is the simplest element known to us, with it’s atom containing just one proton and one electron. It is lighter than air but doesn’t exist alone – it is always found in combination with other elements. Many see hydrogen as the ultimate alternative fuel particularly in fuel cells, but it does have drawbacks, the [...]

Hydrogen-powered fuel cells hold enormous promise as a power source for future generations. Hydrogen is the simplest element known to humans. Each atom of hydrogen has only one proton. It is also the most abundant gas in the universe. Hydrogen has a unique property. It carries the highest energy content of any common fuel by [...]

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 [...]
