Look mom, no wires!

Fuel cell-based notebooks are nothing new to frequent readers of DailyTech. In early June, we reported on Toshiba's early efforts with a fuel cell notebook dock that was able to power a Portege notebook for 10 hours. In October, the company showed off an updated version of its fuel cell dock -- this time with a smaller fuel cell stack that was confined within the footprint of the host notebook.

Samsung is taking fuel cell technology for notebooks to the next level by showcasing a new DMFC (Direct Methanol Fuel Cell) dock that can power a Q35 ultraportable notebook for 8 hours a day for a full month. According to Samsung press release, the fuel cell has an energy density of 650Wh/L and total energy storage of 1,200Wh.

Samsung has also made many improvements to its fuel cell system that reduces noise levels. The new systems has noise levels comparable to current notebook computers which gives Samsung an edge over competing fuel cell designs.

Fuel cell technology has come a long way during the past year. Just last month SAIT and Samsung SDI showed off a prototype fuel cell battery charger that weighs just 5.3 ounces. Likewise, Nokia envisions that fuel cell-powered mobile phones are just a few years away.

im hoping that they just made it that size so they could get the "one month" timeline in there, and could easily make it smaller to power it for say, a few days.


id love to have one that is mega light and could power my lappy for 3-4 days.


or maybe interchangable capacities? now that would be slick.

The problem here is that you need a stack of fuel cells to create enough electricity to power the laptop. The bulk of this thing is probably fuel cell stacks and not fuel. The month of fuel is probably what they considered a reasonable size/weigh/time ratio , given the unavoidable initial size and weight of the item without fuel.

The time is (or at least should be) coming when fuel cells are the power sources for nearly everything portable. If global warming and its delirious effects don't kill off, we may see a day of pebble bed nuke reactors/hydrogen/fuel cell based economy.
