Renewable fuel cells for Electric Vehicles.

Some scientists have succeeded in making the cell's first renewable fuel that can store more energy than petrol. Vehicle-electric-powered vehicles potentially more environmentally friendly than gasoline vehicles because they do not produce greenhouse gas emissions, but the cells used for propulsion can not store as much energy as fossil fuels. Now, Stuart Licht and his colleagues at the University of Massachusetts, Boston, United States, has created a fuel cell-vanadium borides energy capacity of the air with a much larger batteries than current vehicles.

"These cells have an energy capacity of ten times higher than batteries, lithium ion batteries and energy density three times larger than the batteries zinc-air," said Licht, "although all of these battery cells and work in the same way. "

A production electric car GM (General Motors) is called "Volt", is due to be launched in 2010, uses a lithium ion battery that can propel the car as far as 40 miles before having to be refilled. To increase this mileage, GM added a standard combustion engine to recharge the battery if it is weak.

"Renewable fuel cell we made it possible to create a vehicle electric-powered vehicles with no mileage limitation, without a separate combustion engine, and without having to frequently recharge the battery," said Licht. Fuel cells vanadium borides-air requires only air and fresh fuel to complete the recharging process. By using this system, a rider simply stop at a refueling point for fresh fuel and continue the journey back to the cell vanadium borides-air as an energy source vehicles.

Peter Bruce, an expert in the field of new materials for the tools of energy storage at St Andrews University, UK, commented: "Finding ways to save more energy than that may be stored in the tools we have now is an important challenge and solutions -imaginative solution is required. Changing the zinc in zinc-air battery with an anode of vanadium borides is a very interesting experiment. However, this posed some challenges for practical tools, such as battery recharging, and many more scientific questions that need to be answered. "

Licht acknowledged that many more efforts should be done before this fuel cell could be commercialized. "This study is the first study that shows a very high capacity of these cells. Details of machines, systems optimization and production scale development still needs to be developed," he said.
