To have a useful range of 480km (300 miles) or so, an electric car using a fuel cell instead of a battery pack would require around 9kg (20 pounds) of hydrogen.
As for the automotive sector, he says that the first fuel cells will also include a battery.
"The company makes a system called PosiCharge, basically a fuel pump to recharge an electric battery, " writes Brendan Coffey, editor of Cabot Green Investor.
How this happens remains to be seen, but there are four distinct options on the table: hybrid cars, plug-in hybrid cars, battery electric cars, and fuel cell cars.
Hybrids need to be equipped with larger battery packs, smaller and more fuel-efficient engines and a "two-mode system" that uses a pair of electric motors that propel the car at lower speeds.
How about a car that gets 30% better fuel economy, doesn't require a giant battery in the trunk or have to be plugged into the wall, and can travel 600 miles between fill-ups?
In a survey of auto industry executives conducted by KPMG, respondents expected that among electric vehicles, hybrids will have the highest customer demand by 2025, followed by fuel-cell vehicles, outdoing the demand of battery-powered cars.

And so automakers now want to make more fuel-efficient cars, and we now have the advanced battery manufacturing here in the United States to take advantage of that new market.
Presently, the FAA is funded by both the General Fund of the U.S. Treasury and the Aviation Trust Fund, an account that receives a battery of taxes on tickets, cargo, jet fuel and frequent flyer awards.
Battery power is one alternative, but so are hydrogen fuel cells, which offer greater range.
ReGenerators are ruggedized mobile and transportable power systems that use solar, wind, and battery power to provide uninterrupted power to replace or augment fossil fuel generators.

This stack inside a flow battery, where the electrolyte meets the electrodes, looks a lot like a fuel cell.
The fuel-cell on a chip is coming along fast and could well replace the rechargeable battery within a decade.
"This novel electrode coating technique has applications for fuel cells in the newest generation of hybrid cars, photovoltaic cells, rechargeable batteries or battery production for a wide range of green technologies, " said the university's Dr. Adam Squires.

Until now, battery power has been seen as primarily a way to reduce emissions and improve fuel economy, whether with relatively conventional hybrids, like the Toyota Prius, with plug-ins, such as the new Chevrolet Volt, or with pure battery-electric vehicles, like the Nissan Leaf.
Furukawa Battery, the Tokyo-based supplier of power systems , is commercializing a magnesium fuel cell technology that generates electricity using salt water as an electrolyte.
Since July, the growing list of reported troubles aboard the planes include a fuel leak, an oil leak, two cracked engines, a damaged cockpit window and a battery problem.
