combattery | 13 April, 2010 21:50in which the methanol is directly used as the fuel and reforming of alcohol down to hydrogen is not required. Such a fuel cell is attractive because the only waste products are

ACER aspire 5560 battery water and carbon dioxide (the latter produced in small quantities). IBM ThinkPad A21 Battery, Also, because methanol is a liquid Dell Latitude E6500 Battery, it is easier to store and transport than hydrogen gas, and is safer (it won’t explode).IBM ThinkPad A21 Battery, IBM ThinkPad A22 Battery, IBM ThinkPad A30 Battery, IBM ThinkPad A31 Battery, Methanol also has a high energy density-a little goes a long way, making it especially interesting for portable devices.
The team is now exploring whether the new film could be used by itself, completely replacing Nafion. To that end, they have been generating thin films that stand alone, with a consistency much like plastic wrap.
“Our goal is to replace traditional fuel-cell membranes with these cost-effective, highly tunable and better-performing materials,” said Paula T. Hammond, Bayer Professor of Chemical Engineering and leader of the research team Dell Latitude E6400 Battery. She noted that the new material also has potential for use in other electrochemical systems such as batteries.
To test their creation, the engineers coated a Nafion membrane with the new film and incorporated the whole into a direct methanol fuel cell. The result was an increase in power output of more than 50 percent.
MIT engineers have improved the power output of one type of fuel cell by more than 50 percent through technology that could help these environmentally friendly energy storage devices find a much broader market Dell Latitude E4300 Battery, particularly in portable electronics.
The new material key to the work is also considerably less expensive than its conventional industrial counterpart, among other advantages.
Like a battery, a fuel cell has three principal parts: two electrodes (a cathode and anode) separated by an electrolyte. Chemical reactions at the electrodes produce an electronic current that can be made to flow through an appliance connected to the battery or fuel cell. IBM ThinkPad A22 Battery,The principal difference between the two? Fuel cells get their energy from an external source of hydrogen fuel, while conventional Dell Latitude E5500 Battery draw from a finite source in a contained system.
