Fuel cells are devices that are capable of converting chemical energy acquired through a certain type of fuel into usable electricity. The most common type of fuel used in this process is hydrogen. Hydrogen fuel cells are not a new technology, as some would suggest. The technology first appeare...
A hydrogen fuel cell is comparable to a battery in that it can produce electricity without relying on combustion or emissions. But unlike batteries, fuel cells don’t need to be recharged, as long as they have access to a source of hydrogen and oxygen. Because proper battery disposal can ...
In recent years,hydrogenfuel cells have proven immensely scalable and have come to be used in growing numbers of planes, trains and automobiles (if you’d like more information on this, take a look at our articles on each of these developments). For many, however, these fuel cells...
How does a magnetic field create electricity? How does a magnetic engine car work? How did Michael Faraday make the electric motor? How does a jumbo jet engine start? Can a jet engine run on hydrogen? How does electricity create the magnetic field? What process creates the physical thrust ...
At high pressures, hydrogen is predicted to transform to a metal, which means it conducts electricity. One of the prime goals ofhigh pressureresearch, going back to the 1930s, has been to achieve ametallic statein hydrogen. There have been recent claims of hydrogen becoming metallic at room ...
What is electrolysis and how does it produce hydrogen fuel? Electrolysis is a process that is viewed as one of the greenest forms of hydrogen fuel production, particularly when powered by renewable electricity. This process uses the electricity for splitting water into its hydrogen and oxygen atoms...

How does a Fuel Cell Hydrogen Car Work? What is a Hydrogen Car? Discussion Comments Byanon344837— On Aug 13, 2013 Can the hydrogen be used just as a fuel and run as a prime mover for a generator just the same way power is produced in other systems using fuel combustion? What would...
Cars powered by fuel cells are also electric, though they use tanks of hydrogen to generate electricity and power an electric motor instead of banks of batteries. You can read more about them in our separate article on fuel cell cars.
摘要: Bringing together technological experts and policy makers to determine what a hydrogen economy may look like and how it may benefit society, "The Hydrogen Economy: Its Impact on the Future of Electricity" conference will be held April 19-20, 2004 at the JW Marriott Hotel in Washington....
