Research team reports success with low-cost nickel-based catalyst
This sector -- which includes passenger cars, trucks, buses, and rail, marine, and air transport -- accounts for more than 20 percent of America's energy use, mostly in the form of fossil fuels, so the search is on for environmentally friendly alternatives.
The two most promising current candidates for cars are fuel cells, which convert the chemical energy of hydrogen to electricity, and rechargeable batteries.
The University of Delaware's Yushan Yan believes that fuel cells will eventually win out.
They are currently finding new to make them cheaper to make.
