LG will probably be one of the first manufacturers to commercialize their Fuel Cell products, and this will probably happen before the end of this year (it’s October already, so the guys from Lg better start burning some fuel if they want to meet the deadline).
According to some news on the LG Chem website, their 1 litre fuel cells will be able to provide 4000 hours of energy (but they don’t say what the purpose will be), and that is (still according to LG) 8 times more than what the competition will provide.

One 200cc cartridge will be able to deliver power to a laptop (with a power comsumption of 25W) for at least 10 hours. They will also target PMP’s, DMB based devices and PC’s (of course). This is an example of their cartridges.
I sense a lot of excitement and fun in the future with these kind of things!
