Like a hungry diner ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast. The view confirms previous hypotheses and provides insight into how to make the catalyst work better for alternative energy uses.
How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery. Researchers have simulated the conditions of an early Earth in test tubes, even fashioning some of life's basic ingredients. But how those ingredients assembled into living cells, and how life was first able to generate energy, remain unknown.
One reason range extended electric vehicles such as the Chevy Volt are relatively popular is they make use of an internal generator to help let you drive further. The challenge is these extenders are usually gasoline powered, using fossil fuels for their energy source. What if they could be hydrogen fuel cell extenders instead though?
Fuel cells are not a renewable energy source, of course, although they can be tied to renewable energy. But even using fossil fuels their ability to produce electricity through an electrochemical process – instead of combustion – can make them flexible, relatively clean and efficient energy producers.
Providing auxiliary hydrogen power to docked or anchored ships may soon be added to the list of ways in which hydrogen fuel cells can provide efficient, emissions-free energy.
Energy researchers at Humboldt State University, in California’s North Coast redwood country, describe their county as an "energy island."
Those Bloom Energy fuel cells that eBay said it will use to power its new data center in Utah? They'll run on natural gas. Likewise most Bloom Boxes going in these days.
Often when we talk about range extending technologies in electric vehicles, it is based upon the assumption that a gasoline powered engine will be behind helping to go longer distances.
A team from the University of Central Florida reckons it's found a way to make hydrogen fuel cells much cheaper to build - and more efficient.
Last Fourth of July weekend, the U.S. Army‘s Tank Automotive Research, Development and Engineering Center (TARDEC) in Warren, Michigan experienced a power outage that halted operations of its laboratories.
Fuel cell technology has been steadily making the transition from research and development to commercialization over the past year.
Case Western Reserve University scientists say they've taken a big step towards the creation of insect cyborgs by discovering how an insect’s internal chemicals can be converted to electricity.
Apple appears to be looking at the possibility of powering notebooks using hydrogen fuel cells - potentially giving them a battery life of weeks.
How can scientists and manufacturers make fuel cells and fuel cell technology a viable and affordable alternative to fossil fuels?
A couple of grains of salt could be all that's needed to help bacteria produce hydrogen from wastewater or organic byproducts.
Southern California drivers who are on the transportation cutting edge - tooling around in hydrogen fuel cell-powered vehicles - will soon have a new option for filling up.
Four fuel cell and hydrogen storage research and development projects are getting a $7 million boost from the Obama administration.
First there was the Hornblower Hybrid, a revolutionary vessel that began plying the waters of San Francisco Bay in 2008 using a combination of solar, wind and diesel power.
No, it's not a breakaway movement from Steampunk - it's serious science. A group of materials scientists have developed a new type of fuel cell that they say could soon lead to methane-powered laptops.
Toyota reckons it can get the retail price of a hydrogen-fueled car below the $50,000 mark, and could launch as soon as 2015.
