Matsushita Fuel Cell Battery for Laptops
Matsushita Battery has made a prototype for fuel cell use in laptops and demonstrated it at CES 2006. In this demo, they had a fuel cell mounted on a laptop computer (a custom built one by Matsushita Electric known as “Let’s note T4″).
The prototype was able to run for 20 hours continuously by using 200 cc of fuel. The fuel cell uses methanol with a concentration of approximately 100%. The fuel is diluted outside of the cell before use.
The fuel cell has been able to produce an average of 13 watts and up to a max of 20 watts.
Obviously, this is just a prototype and a lot of work need sto be done. Matushita plans on having the product commercially available by 2010.
Imagine your laptop running for 20 hours off one battery. Not bad.
